I like factory stock too. I've had 3 sets on my Passat. The original, the original to the '01+ and then upgraded to the 16" '01+ rims. I was tempted to try some Audi rims but then I'd have to find VW center stickers.
I've seen some nice aftermarket. I hate the big chrome look

Usually I prefer factory ones. Mostly because when aftermarket weels are chosen they are bigger and with thin tires, which I do not like.

definitely factory stock ones - as they should be then found only on same car models as you have. Not just some BBS' on every car from Fiesta to SL55...

Depends on the rims, so stock for now

I prefer the Factory Stock wheels myself.
