I spent $35k on the camaro, I've spent ~$6k on engine work, and I'll probably spend about $3k on suspension work...
Even with the extra weight of the $20k I'll have in the trunk...I'll still eat that M3 alive. (I've already fed an M6 to it...so an M3 would just be a snack.

)
BTW...I'm a former E46 M3 owner that wanted the new E92 M3, but was not willing to part with that much money when the other options are REALLY close for allot less cash.
I know all the things that I 'gave up' with the M3, but to me it wasn't worth the extra coin...it's damn close to P-car territory $.
