When's the last time you bought a car and they told you about every time they smoked a pothole or scraped the underside of the front bumper or that time a friend puked in the back and they had to clean it up, or that time they bagged the sh*t out of it or how many times they have launched it? Do you do that when you sell your cars? Nobody sells a car and volunteers that kind of information - the exception being major damage, major known issues, etc. which would show up in an inspection anyway. The fact that it was chipped would also likely be revealed in the inspection.This quote is hidden because you are ignoring this member. Show Quote
If they ask a specific question and you lie, THAT is where it becomes an issue, both morally and probably legally. As far as choosing not to make the Kijiji headline "Previously Chipped Q5" well I don't think there is any obligation whatsoever to do that, nor would that be the norm on the used market, and especially if the vehicle passes an inspection and is left in original operating condition. When I sold my old chipped S4, the extra power was a positive selling point and it sold almost right away, but prospective Q5 buyers are probably a different demographic.
To the OP: I would go APR, they know Audi and make a good product with a good reputation. My experience with them however is a little older, but I had a 2000 S4 that was chipped for over 130,000km with not one single issue. Just make sure your transmission can handle it, that is the only thing that would make me worried.
