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.

The "used car dealer" method is not one that Alex uses.
The "used car dealer" method is not one that Alex uses. He won't try to upsell you a car, but he will provide you the facts you require. He responded to texts and phone calls really quickly. The Explorer required a few additional repairs, which Alex and his technician promptly fixed. His willingness to ensure the car was ready for use was really appreciated. There are some unfavorable reviews here, but since we're purchasing secondhand autos, problems are inevitable. Those evaluations shouldn't stop anyone from seeing one of his vehicles and getting to know him in person, in my opinion. Alex was a great experience for me, and I think you will be too.
Pure luxury
This Audi is beautiful, inside and out, with genuine wood in the door panels, dash and center console, soft leather seats, and a massive amount of red light illumination throughout the front cockpit, that is fantastic while driving at night. The exterior is sleek and stylish. The ride is smooth, however the low profile tires do ruin some of the ride atleast on kansas roads that are far from smooth. The engine has no vibrations and suspension seems tight . All in all this is as close to perfection as it gets, German cars are the best.

Only place that helped us
We had a poor credit rating, and Advanced Auto Sales was the only place who gave us hope. Everyone is very nice and knowledgeable salesman and finance. When we went to pick up our car, everyone there was happy for us. I highly recommend them.
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.

HIGHLY RECOMMEND
HIGHLY RECOMMEND. This was one of the best car buying experiences I have ever had in my life. I recently purchased a 2017 M3 from Foley Motorsports, which is my 14th vehicle purchase. Foley was able to give me a great deal on their vehicle, and gave me a very fair offer for my trade. I was able to negotiate, purchase, sign and take delivery all on the same day! I was literally in and out in an hour (mind you its a pandemic so things certainly aren't AS busy as usual...) RJ and his staff are very efficient and are sure to not waste your time like most dealers do! If you're in the market for a used vehicle, CHECK OUT FOLEY MOTORSPORTS!

Absolutely outstanding service!
Absolutely outstanding service! From start to finish, the team at Carmart was professional, knowledgeable, and genuinely helpful. The car selection was top-notch, and the purchasing process was seamless. I couldn’t be happier with my experience and highly recommend Carmart to anyone looking for a reliable vehicle and exceptional customer service. Five stars well deserved!
Perfect sports sedan, TDI engine is amazing!
Bought my '16 A6 3.0 TDI a year ago with 89k miles, now has almost 110k miles, and drives like a dream still. Can't even tell it's a diesel engine by the way it drives and how quiet it is. I drive a lot for work, and the gas mileage is amazing! Interior is comfy, classy, and roomy. Drives like butter, handles like a sports car. Exterior isn't too flashy, it's perfect. No issues, and my last checkup at the German export dealer was perfect. My favorite car I've owned, now I want an A8 L!

Although Audi of Burlington is where I purchased my Audi
Although Audi of Burlington is where I purchased my Audi I had my Q3 towed there as a tire fragment hit under my vehicle and damaged my oil maintenance sensor. Derek at the service desk immediately took care of me by providing a loaner car for my ride back to Cape Cod, called me when I got home and explained the process to fix my car providing a video of the damaged area and a thorough explanation of the work involved. All people I dealt with there were extremely nice and thorough.
