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!

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.
Very nice upscale vehicle. Bought as a previously
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.

Top-Notch Customer Experience
I can not say enough about my experience at Long Cadillac. I was referred by a friend that has worked with Long over the past several years; his referral was nothing short of spot-on. The atmosphere at Long sets the gold standard for what every car dealership should strive for. My Sales Associate, Ron, greeted me with a smile and was eager to answer my questions. He was extremely knowledgeable and took the time to understand exactly what I was looking for. During our visit, we were also warmly greeted by Tom, the Sales Manager, who solidified that we were truly in the right place. On the day of pick-up Ron remained in contact with me to ensure a seamless transition. When I arrived at the dealership he had the car ready and was excited to go over every inch of my new vehicle. Even after leaving Long, the experience hasn't ended. Ron has remained in contact with me to answer any additional questions and to ensure I?m completely satisfied. All any customer wants is to feel valued and listened to; Long Cadillac certainly drove those feelings home. They deliver a top-notch customer experience and have certainly gained a lifetime customer in me!

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.

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!

Excellent choice
This is a fun, responsive, reliable, well built car to drive. At over 75K miles now, and I really cannot even consider trading it in because I don't think I will enjoy a better ride.

IMPRESSIVE SERVICE ORGANIZATION
I had my Audi vehicle towed to the facility with a transmission issue. From intake to diagnosis and repair, the staff, at all levels, performed in a professional and personable manner. Their communications throughout the process were timely and thorough. The Audi Warwick service team sets a high standard for all auto repair organizations to emulate.
