For parts sites. Mostly exterior stuff, ECS doesn't have a lot of replacement items. And BFI has close to nothing. Any ideas? I have a B4 wagon by the way.
Not too much in the way of exterior stuff that I'm aware of, I'm sure the others are aware of some more sites. For now, in the way of stock items, try these.
http://techtonicstuning.com/main/ No body parts, but if you're looking for aftermarket or stock engine stuff.
And for stock replacement parts, you can always try RockAuto. In fact they just sent me an email today regarding wholesaler closeout parts for 2.0 B3s... Wholesale Listing
What parts are you looking for?
Forget projector headlights. Get Hella ecodes, NOT Depo.
Don't US B4 Passats have amber headlight corners? The middle section at least?
