The wheels hold up decently, I think. I refuse to run them in winter (if you live somewhere that has such a season!) because I don't want the finish attacked by salt and ice and all that junk.
Otherwise, I've rocked the Euros for 2 late spring/summer/early falls
and they look rather good. Well the 2 passenger side ones each have a little paint scratched off on account of a Close Encounter of the Curb Kind
but the drivers ones still look rather pristine.
I keep them waxed and clean the brake dust or any grit off them about every 2-3 weeks while they're on... then after I take them off for the winter and before I put them back on in spring. I would say they're good, they don't chip if you look at them wrong or anything like that! Oh and on the passenger ones, not a sign of denting, they seem to be a stronger alloy than the notoriously soft 5-spoke SVTs.
