Got a nice 2017 Q7. Nice car even if controls are not intuitive. Unfortunately unethical salesmen spoiled the whole experience. Ordered the car with just what I wanted on it and when it took 3 1/2 months to come in. Then I got cheated on the trade in. They had promised me $23,000 in the contract subject to my trade in "not having a lot more miles or any mechanical issue or damage". There weren't many more miles or more issues but they still told me it was only worth $20,000 but would do me "a favor" of giving me $21,000. That may be the right value but the problem is the $23,000 they originally promised me was never real and just made up to make a sale. I expected better than a sleazy bait and switch used car salesman trick. I was wrong. Won't make that mistake again. This is my 3rd and last Audi I'll buy from them. They ripped me off.
