Hi, I have read the tuning measures several times can reduce the value of vehicles. From when does this impairment occur ? As soon as a spoiler lip is on the vehicle ? As soon as the chassis is changed ? Thresholds are installed or does it already have a foil grill on it. I get the money that I put in the tuning parts at the resale actually partly out or even reduce the resale price. Please don’t get me wrong now (especially madze, ic h find your pelican totally beautiful, the same goes for DSGTOM + which I have now forgotten.). Please have a few thoughts on the topic and tell us about your experiences, such as when selling back to dealers or private individuals. Has the tuning paid off or even had a negative effect? From when is an A3 “basked” in your eyes. Many greetings g-j
