Of the two, I am definitely a fan of BBS wheels. I love the LM-R. Sorry to say though, the AVS just doesn't do it for me. I think my current two prospects for aftermarket are the BBS CH Black line and then followed closely by the Advan RS. Although I'm currently really digging the oem 18s... I might not be able to move on from them... I have issues, I know.
I was actually dealing with Edmonton BMW for a month or two before I finally pulled the trigger on my M3. The parts rep was pretty gungho when the sales rep asked him to show me the Dinan 335i. I really want to see the guy that actually spends $80K on that when he can have an M3 instead. they were really pushing me to make an offer.
