Dents and chips don't bug me for some reason (and I just don't worry about my wife's A8), but the two things that really *do* irritate me are:
-The crappy paintwork and flawed driver's door glass on the S8 from the deer-incident repairs
-The scratches (paint, too deep to fix; chrome; even glass) and other cosmetic issues on the Jag, which have bugged me for 21 years now, ever since I took new-car delivery
Some day I'll get the S8 repainted, if I can ever find somebody good enough, but the door glass is a weird thing. The Jag can't be "fixed" without a full restoration and then it wouldn't be my original XJS any more.
My two favorite cars, my two "keepers", and they can never look better than mediocre no matter *what* kind of good detailing I do
Anything else, on any other vehicles, I either get fixed to my satisfaction or I'll just replace the vehicle, but no such simple solutions on those two.
