Quick efficient
Vaani is amazing and has spoiled it for other dealerships! He had vehicle options for me and sent them to me to review prior to arrival. When I arrived the cars were available for me to look at and he accompanied me on the test drive pointing out major & minor features! I already had a Mercedes but was considering buying a non Mercedes (crazy huh) but the dealership I went to was not welcoming and more like I was an inconvenience. Very appreciative of the quick efficient process and I Love my new car💕
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

Made me feel like family as soon as I walked in very helpful and accommodating to my needs didn?t feel rushed at all great staff and location overall.
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

I drove from Meridian, MS to Birmingham, AL to get my car
I drove from Meridian, MS to Birmingham, AL to get my car because of the awesome customer service from the initial phone call. Abdul was heaven sent! He not only got me into the vehicle I wanted with the price I wanted, but also coordinated dropping off my rental I was driving, bought us food, and even checked on us driving down to make sure we were safe. The whole process was easy and he paid attention to the details of what I wanted. All the staff were friendly and treated us with kindness. Abdul truly cares about his customers and I will continue to be a customer.
Great Electronics and Engineering
This car is state of the art in human factors engineering. It has multiple layers of safety enhancements. Interior is very spacious. The 42 volt battery provides quick acceleration which allows the car to have no lag time when accelerating.

I just bought my new 2026 Mercedes-Benz GLE 350 from Mercedes-Benz of Foothill Ranch, and the experience was amazing! Sean Roslon made everything smooth, stress-free, and enjoyable from start to finish. The whole team was friendly, the dealership is beautiful, and they even have an awesome coffee machine that makes the wait way better! I absolutely love my new car and highly recommend Sean and the Foothill Ranch team!

I'm floored by the bad reviews of Discovery Auto.
I'm floored by the bad reviews of Discovery Auto. I almost didn't go because of it. However, I had my heart set on a Cadillac they had. I live in Clearwater so its about a 45 minute drive. I called the sales line and got Maurice. I told him exactly what I wanted. He desperately tried to get me the deal. However I know that dealership was telling the truth about that car because I had been looking at that model for 2 months. They did have the best price hence why I drove out. Unfortunately I couldn't talk them down but the manager Jonah came out to tell me why. I didn't feel like he was lying because I have Google and verified literally everything he said. So I moved down a notch to accommodate my budget comfortably. And I LOVE my new Camaro. I also want to say that the dealership has cars that will blow you away. Ferrari, Maserati, Mercedes-Benz audis, bmws, literally every high-end car you can think of and they are clean- clean. But back to the bad reviews. I saw one review that a lady was upset she only got one key. I only got one key to my car. So I asked my salesman where's the other key? And his response was we can't control what the previous owner brings in. Which absolutely makes sense. My previous owner also didn't bring in the owner's manual. But I can't fault the dealership for something like that. I also saw a review that somebody gave him a one-star because they didn't get approved. That is not the dealerships fault. I'm not saying that they didn't feel slighted. But I HATE being lied to. So with that being said... go check it out for yourself. Ask for Maurice.

2017 Honda Civic
I bought a 2017 Honda Civic last week. I was preapproved before I walked into the dealership. There were a couple of issues once I began completing the buying process, but after 3 hours at the dealership, I walked out with my new vehicle.

Metric has some top of the line cars on their lot.
Metric has some top of the line cars on their lot.I did my research through CarMax and choose to get the Lexus from Metric, and was approved in just a little time. The car was beautiful, clean , low mileage, and had a really awesome price tag. I would send my friends and family to buy a car from Metric. Their customer services was great and very professional. The ball was in my corner, they made me feel that I was a valuable customer. Thank you Metric Dealership of Raleigh.

ACURA INTEGRA A SPEC TECH
Secured an offer, caught the Amtrak from Fresno Ca to Stockton and purchased the vehicle. Was in and out within an hour. Other dealership in my area didn't want to give me a good deal, though I'm not asking for a steal I just wanted a better deal on a new vehicle and Stockton Acura took care of me. Would recommend Acura of Stockton to anyone who ready to purchase.

I sold my Kia Soul to Carmax a few months ago.
I sold my Kia Soul to Carmax a few months ago. The offer was at the price I was asking on other sites. My Soul had only 33k miles on it but pressures from my mom made me sell it. The offer came via text message and it was a super quick sale. The check was deposited without issues. It was all very smooth.
