Stone chips are a worry, the surround to the wing mirrors are the most vulnerable as to make the finish smooth alot of paint had to be put on it. Although the man who did it had paint left an gave it to me in a tin so i can fix any chips.
I have also taken to parking my car far away from other cars, sometimes even in two spaces

because i don't know how the painted rub strips will hold up to some ignorant ****** opening the door of his 20 year old heap onto my car. lol
I love my alloys, although if you get them i would advise not getting the same profile of tyres as 35s are too small!!!!
