Really sorry about the M3, man.

If you still need some engine bay decals, call La Jolla Independent BMW Service, their website is Bimmerdoc.com. They're good guys, specializing in E9s and other vintage Bimmers. They reproduce all kinds of decals for BMWs.

I think there's also another user on R3v who does the same thing, I'll try to dig up his SN.

I hope you get a fantastic paint/body job next time around!
