Very nice upscale vehicle. Bought as a previously 2 yr leased auto, avoiding new car price and immediate depreciation. V-6 engine has no hesitation and quietness is excellent. My only two negatives are lack of storage for incidentals and a bit quirky audio that may reset from time to time ( must wait for it to go through a cycle). It has a mind of its own. Overall, excellent vehicle.

Not enough communication before the service, and too much
Not enough communication before the service, and too much after afterward. One phone call from the dealer or one survey should be sufficient. Its too much.
Beautiful Meh
Leased the car for looks new in 2021. Now 2023 with 28k miles. Perfect? No. Awful? Hardly. Many recalls but no maintenance issues whatsoever. Biggest complaint is the auto-start stop and that the electronics are quirky (pre-set destinations reset frequently) car is comfortable, quiet, quick, and get OK gas mileage (would assume better with 2.0 4cyl.) I often switch between this and a 2017 Honda Accord and to be honest I can't tell much of a difference other than noise and quickness. Will buy it off lease (got it before the residual values rose exponentially) and will keep it indefinitely.

Satisfying experience
I have purchased two vehicles from Carmax I did not feel I was being taken advantage of. I received more for my trade in than expected. I have recommended them to friends and family.
Just purchased
I originally owned an Audi A4, which was an excellent vehicle, very reliable. I expect no less from the A6, which offers all the latest in safety and convenience options. So far I am very pleased with the car and I am only scratching the features it offers. Great ride.

It was an excellent experience.
It was an excellent experience. The overall process was great, with customer care and efficiency. Digno made a huge difference by ordering to fix small scratches the car we were buying had. He did it without us asking. Thank you for all your help. The finance manager was also superb
Love this car!
Got the premium plus with Executive pkg, black optic and V6. Love this car! Only had it a week, but happy with the purchase. Was originally looking at Mercedes as I had one for 13 years, prior to my Jeep. Price and drivability was superior with the Audi for all the features I wanted.

My Best and Easiest purchasing experience ever.
My Best and Easiest purchasing experience ever. From start to finish the staff were polite, friendly and professional. Denzel was exceptional going above and beyond to make sure I was happy. It’s the kind of business that you know is well run because the staff reflects the managers traits and is passed down. I highly recommend

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.

Dylan Starr was great. We set up an appointment to view a vehicle and went to check it out, it’s good to have an appointment in case someone else who walks in is checking it out as well, you will get priority. The experience was very good. Thank you guys.
