Carlos was the man – his customer service was great and efficient. He answered all of our questions and helped us with the financing and deals! We had a legit experience. The truck has a coolant leak we informed them about. They ordered the part and it’ll be fixed at their Escondido location Monday with no charge. We drove the truck home to San Diego and didn’t have issues. So far so good / will update if anything changes. Thanks Carlos!!!!

The service was good. The sales rep. Federico De La Fuente did explain everything in full detail. And was able to answer every question. Very knowledgeable he actually allow us to take our time in inspecting the car we choose. We are happy with the service and the vehicle we choose…

SHADY SHADY BUSINESS!! DO NOT COME HERE!! I have never written a review before, send I am not the type to either, but I have to let it be known. it took me 2 weeks to get my refund AND my ID back!! My ID for Christ sake, they kept it in order to pressure me into buying a car I didn’t want to buy anymore. When I went back the 4 time in two weeks, they finally agreed to refund my money (I had to go back a week later and argue with the manager because they never actually refunded it) and as for my ID card, this man pulled out a STACK OF IDs and flipped through them until he got to mine.. A STACK. It’s how they pursue you into buying a car, by taking your ID AND pretending they can’t find it. If I wouldn’t have fought for my money and MY ID, I NEVER would have gotten it back once you sign that paper, they get rude and disrespectful, I have it all on video.. .. shady place. Don’t come here.

Federico had excellent service, went above and beyond to find something to fit my needs and budget. Explained and walked through everything thoroughly.

Thanks to Alex Ayala for making my first car shopping experience a breeze! He is a very knowledgeable and negotiable man I’ll definitely be recommending quantum auto sales to my friends and family!

I am writing this review, because of my recent visit with Quantum Auto Sales! Let me tell you, I had been stressing out about finding the perfect car for myself as a hard-working professional. I needed something safe and reliable, as well as great priced. I was not able to find a car dealer within my area that would work with my increasing credit. However, Quantum auto found the perfect car loan for me and was able to get me into a car with, good miles, reasonable price, safety, and comfort! I was more than thrilled to work with Aaron he was very professional, reliable, firm, but understanding. Jose the financial advisor, made sure I got a reasonable monthly payment for my budget. These guys know exactly what they are doing, give them a try! Thanks for everything Quantum Auto!
Mr.Mrs. Aragon#1
Aaron was great, he gave me the best deal. I recommend everyone who comes asks for him. He’s polite well mannered and very great to work with all around. I am more than satisfied with the help got from him and highly recommend Aaron here at Quantum Auto Sale’s

Mando Castro
Worse service ever!!! We got a car here and the next day it didn’t start, we called the mechanic so he could fix it.. car was not supposed to break down the following day even though it’s a used car like the mechanic said… “ the mechanic “ wouldn’t give me an appointment to bring the car to the shop so he could “fix it” If you wanna avoid something like this from happening to you DO NOT come to this dealership . I have found Other problems with this car that I have explained to different personnel from this dealership. P.S you should not tell the customer “it’s a used car” we know it’s a used car but it shouldn’t break down the following day, it’s supposed to be in good conditions even though it’s a USED CAR!

DO NOT BUY FROM HERE! THEY ARE A SCAM AND TAKE YOUR MONEY! My family went to purchase a car and not even a week later the car was having issues! We’ve had to go back 4 times already for them to “try” to fix it. They also lied to us about the down payment. They told us something different when we were purchasing the car and 2 weeks later they call us saying we need to pay an EXTRA 500! The general manager Jorge is also very rude! He kept making comments as if we didn’t have enough money to be able to afford a car!

Celeste Ramos
Amazing customer service! I highly recommend this place if you’re looking for good quality and reliable cars. Ask for Carlos he will most definitely help you out no doubt. Great place, thanks again!
eren hernandez
Tony Gonzalez was amazing! He went the extra mile to provide us with excellent customer service. We were literally in n out. He was helpful and walked us through step by step. I highly recommended him, first time buyers, bad credit. He works with you and guides you. Thank you Tony
Maribel P
DO NOT BUY FROM HERE! When you’re purchasing a car they tell you a different amount that you need to pay for the down payment. Later they call you saying that you need to pay MORE MONEY! Do Not Purchase A Car Here! This dealership just wants to get money from you! Also Jorge, who is the general manager doesn’t do anything to help!!
Angel Medina
Worst place to buy a car customer service its a shi… even they don’t use mask and when you sign contract they hold for 2 months the registration and sticker and plus when you ask a question nobody can answer and they say wait until the manager comes but the manager never comes
shavon wright
Aaron was a fantastic sales man. When I tell you he got me exactly what I wanted with no hassle. Very professional and fast service. This is my number one recommended car lot in the OC. Ask for Aaron if you drop by and say I sent you.

Tony Gonzalez was attentive, friendly, helpful with options n even showed us diff inventory from two other lots.. we walked off with a car we loved and at a great price!! 👍👍
Fernando Suarez
Ask for Tony he is a great sales man. I went in looking for a car and had bad credit and he was able to walk me through and get the car I loved within a day. He was very patient and made sure I saw all options of the Mazda CX-5 before I made my decision. He wasn’t pushy at all and very understanding and helpful. I recommend this dealer to anyone looking for a nice car with low miles just ask for Tony!
Nuvia Rivera
Great people. They will do anything in their power to help you get what you want.easy finance with the banks.first time buyer and I am satisfied with what I was approved for. great staff
Dinh Tj
Definitely worst auto experience. Cons: •Bad customer service. •Sales men who lie. – tell me to come in to get my car detail but service department says no. •Service department- very combative when talking to regarding service. They did not want to help me at all. •People at quantum definitely just looking for the sale. After you leave the lot, customer service out with it. •Best chances to take another car dealership. The attitude and atmosphere definitely not something you want to deal with especially on a a car investment. •If I was probably Hispanic, they would have given me better service.
Ximena Palacios
My experience at Quantum Auto Sales is by far the best, Guillermo and Fredys exceeded on giving my mother and I the best customer service! They were attentive and friendly. I recommend for everyone to come to this dealership, you will not regret!
Jazmin Gonzalez
Anthony really helped me out here. He has great charisma and was very polite. I would definitely go back when the time comes to buy another car. Great deals and great service by him.
Carlos helped me get my car and he was super helpful and patient with me. He explained everything throughly to help me chose the perfect car for me! Would definitely recommend.
Justin Gerodias
We end up having such a great deal here. We did not plan on buying, yet we ended up buying a car we like due to such a great deal we were offered. A man named Aaron made sure that we buy the right car based on our preference and budget. Even if you do not have any credit, nothing to worry! They got you covered. I’m not sure how they do it, but they magically work things around. After all, I’m very pleased to have came to this place.
cinko mac
Maan ! I was in need of a car . I sent Aaron my information after hearing about how professional he was and how he really worked with a friend of mine . He took of the paper work and told me to come in. We were there for a hour and a half and me and my family drove off in our new car . Aron is the best and Quantum Autosales are legit . I highly recommend them even if you live far away IT IS WORTH THE TRIP I PROMISE YOU 🤝

This was a terrible experience, almost felt threatened with the bullying both the boss and his sales rep committed. I wanted to test drive and I have a credit score of 693. These people made me fill out all information and pulled my credit score (by promising it’s a soft enquiry when it was actually a hard enquiry) by lying straight to my face. The guy actually has the audacity to tell me that you have a baby credit history. And when I tell him, you have my credit score, which is decent, then let’s do the test drive as it’s been 40 mins already and I have still not seen your car let alone decide if I want to buy it. And it gets better, the guy tells me, “for someone who asks a lot of questions, you don’t like answering any huh?” I am not going to use insults and will only stick to facts as that’s what an honest review should be. I had the money, I would have bought it straight away, with the help of my bank. but because of such an indecent behaviour, almost insulting, I think I will ensure none of my friends in OC or around go back to this establishment. Peace.
Carlos was really helpful and honest with everything that was given to me regards paperwork. I appreciated his customer service and the way everything was handled.

I really thanks Aaron he is the best salesman ever, he helped me get my 2016 Mercedes Benz, thank you for everything will send you customers
Natali Garcia

Yen Manalili
I highly recommend this place , I left this place with a good smile and family . I would like to thank Aaron Ruiz , he’s the best salesman ever. The staff are all nice and helpful. If you decide to get a car and your not sure with your credit , we’ll this is the right place for you . And look for Aaron Ruiz
William Goodman
This place is just incredible with such a nice inventory of cars, trucks, and suvs. When we arrived we had no idea of the amazing customer service we would be receiving. Aaron went way above and beyond to make sure that we were satisfied with our purchase, not to mention the great patience he had to possess from dealing with us. All questions were answered fully in detail, and the deal we got was absolutely unheard of. If you want an amazing car for the best price with the best customer service do yourself a favor and go to Quantum!! Very happy customers right here!
Mitzi Gonzalez
Really great service. Anthony helped me and really listen to what I was looking for. If you need someone to help you I would suggest to ask for Tony. He was really great.
Lidi Garcia
Miguel was our sales guy. He was very patient and helped us find the perfect car we needed. We would definitely recommend our family and friends to this dealer and to for sure get helped from Miguel. He’s awesome 🙂
Steven Smith
Horrible customer service! One of the employees can’t speak english, the other employee don’t know anything about cars, and the rest pretending like they’re busy or on break at 10am and this is base on my first experience walking in. I can imagine if I were to have any problems with my first purchase.. Stay away ppl or better yet buy at your own risk!
My husband needed a work truck so we started researching online…as much as I hate going to car dealers we decided to give Quantum auto sales in garden grove a try… the staff there was very professional & helpful….not pushy like the bigger car dealers…Nica and Brenda went above and beyond to find a truck my husband liked within budget, we drove it and decided we wanted to purchase… once financed they cleaned the truck for us and we were on our way..Thank you both for making this happen.
Evy Tejada
4th car I buy from Miguel! I love that I can be straight forward with him and he is the same with me. I tell him what I want and he makes sure he finds me the perfect car! Thanks Miguel my husband and I are never disappointed
Paulo Mercator
No english speaker sales person. The advertised car, one of the best cars in the market was horribly kept, convertible top not working, trunks panels all over the place to fix some major eletrical issue. The car is advertised as premium with the highest price. I wouldn’t give them my business.
Jackie Aguirre
Today we spent the whole day searching for someone to approve my husband who has little to no credit. We finally got referred to Quantum Auto Sales and our sales person Miguel Martinez helped us out tremendously. We appreciate the work Miguel did you get us the car we wanted . Highly Recommend
chris Fuentes
Just came to this place cause the guy was like yeah sure we can help and they wanted me to give my car and a large down payment stay away from this place if I could give negative stars I would
Jennipher Herrera
Because of Aaron, I got my first car today. He had so much patience to help me choose my very first car, and I came out with the best one. Thank you so much Aaron.
Elvis Guzman
Trash dealership and rude service. Avoid coming here. I was able to purchase a car through the dealership and signed everything to finalize The agreement but 20 days later they called harassing me to return the vehicle because I supposedly didn’t qualify when they told me at the time of signing that I was already qualified. AGAIN, AVOID COMING THIS TRASH DEALERSHIP
Lemar Wali
Very professional dealership that will work with anyone with bad credit. I went to other dealers who were incapable of finding me a lender. who got me approved with out any hassle. Mike was an awesome salesman, hands down.
This rate is for Aaron, I want to take my time and thank you for your help, you made it happen to get my wife’s dream car! You are the man! I highly recommend Quantum, they will work with you. Thank you Aaron!
Benjamin Bartoli
After being turned down for an auto loan at a Chevy Dealership, my wife and I were referred by a friend that claimed Quantum Auto Sales would help me get the truck I needed. I called and Immediately got a call back from Carlos, who got me approved over the phone, and sent me pictures of the trucks they had a available. I took a Lyft to Quantum yesterday morning and drove home in exactly the truck I was looking for! I’ve purchased many vehicles in my life, however this was the easiest and most friendly service I’ve ever experienced! The sales staff went above and beyond searching their inventory, and Carlos even drove all the way from Gardena to San Diego and back because I selected a truck that was at their San Diego location! Thank You Carlos, and Quantum Auto Sales! You have a customer for life!
Cesar Zavala
Nica’s Service was exceptional, quick and easy no hassle we were in and out with the car I wanted insurance and everything. Definitely recommend to stop by his manager was also great customer service.
Dark Hawk
Amazing service. I always do my research before going somewhere (pretty important) and so far was one of the best ones. I tried them out and honestly they helped me really good. Great customer service and the car even more! Thank you Quantum for my new vehicle
Timothy Trapp
Arron was the man!!! The gentleman knows what he’s doing , he must be voted salesman of the year i love my new explorer ty Arron, George and the rest of the Quantum team satisfied customer Timothy Trapp
Maria Romo
Aaron thank you so much for helping us find our new family car! You made this experience easy from the start and made sure we got everything we wanted! Next time anyone in our family needs a car, we’ll make sure to go to you!
Priscila Oliva
Came in thinking negative about not being approved because everywhere else was all ways a negative! But not here I’m sure we got the best worker in the place because he was really honest and explained everything step by step! Thank you so much El Nica Delgadillo best sales representative, I have ever met🙌🏻😎
Arthur Maldonado
DONT COME! AND DEFINITELY DONT LEAVE A DOWN PAYMENT! The cars look all nice but drive it a few miles and it’ll start shacking and things will start malfunctioning. Seriously go to a professional at Toyota or Kia because you really will get what you pay for. Don’t get me started on how long it’s taken to settle a finance agreement after I’ve sent ever single document they’ve asked. If you don’t want someone coming to your work or calling your whole family for a form that they lost; then JUST GO W A PROFESSIONAL. Avoid Miguel. Very very rude when no one is looking.
Getting my first car was so easy, had help from Tony best sales rep ever. He made sure I was completely happy and comfortable with what i was buying. Thank you Quantum
