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!

The staff here is tremendous!
The staff here is tremendous! Not a single staff member walked by without acknowledging my wife or I. These guys know how to make someone feel welcomed here, the stigma of having a car salesman be pushy doesn’t exist here! Our sales man David Escobar helped us find the perfect suv and worked the perfect deal. Can not say enough good things about him, worked through everything, explained everything thoroughly and then some! Bottom line if you’re looking for a new vehicle and don’t want to deal with the drama this is your place to be without question.

Had a really good experience buying new car.
Had a really good experience buying new car. Daniel O. Was really knowledgeable salesman on the Audi as well as competing brands. I was able to take his feedback to cross check and Daniel was spot on. Paper work was painless and I was able to complete the purchase in a couple of hours unlike past experiences at other brand dealers. Overall I thought the Audi team was awesome and look forward to my next buying experience at Westmont Audi. Great job
Brilliant Car, expert servicing
Excellent car, just done 122K and runs like a dream, had it serviced regular by brilliant guys at the general motor company in Stockport in UK. Didn't want to trade in when lease finished. Looking to get many more miles Peter Gilligan

Quick and easy ,traded in 2015 tdi q5 turbo diesel white
Quick and easy ,traded in 2015 tdi q5 turbo diesel white was fantastic car ,but decided to get a new q3 Quattro s type ,very nice reliable suv we keep our cars a time
Better than my first Audi
I have owned this car for just over a year. No mechanical problems, very fun to drive. Took it across the country, very comfortable for driver and passenger. Loves to cruise at 75-85 mph and will go much faster. I thought I got a great deal on it. I paid half the sticker price and it had under 10,000 miles on it.
