It should run you about $150-200 per wheel for a good job. Powder coating is the way to go. Much more durable finish so the wheels wont chip like painted ones do. You can go either flat or gloss black, its up to you.
You could scoop up a Carrera GT and a GT3 for $400k if you do so searching. Or.... F430 Scuderia + R8 V10 599GTB + GT3RS GT2 + M3 + Exige Viper ACR, 'Vette ZR1, GT-R, + A Daily Driver (M5, CTS-V, etc.) etc. etc. etc.
Its too hard to choose one, they're all pretty great cars. All my cars have been pretty heavily modified, but the stock E92 platform is probably my favorite so far.
Beating the living hell out of it. Took a dip into a wonderful NYC pothole which swallowed up the VRS lip, so the front end is back to stock. Stock 19's have been replaced with HRE Monoblok's and a Brembo BBK. Other than that, nothing has changed on the exterior. The interior is stock except for the alcantara BMW Performance steering wheel with digital readout If weather permits, i'll have some new pics this weekend.
Lkpt, do you have a Costco membership, or know someone who does? I've heard from quite a few people that they have gotten cars through them for barely over invoice. Seems like a good way to go if you dont like, or know how, to haggle.
