I just wonder if there's a Chev equiv to ImportMonster.
They have multiple websites and companies of a similar fashion, it's a case of how much do you want to spend. These days you can pretty much build a brand new '32 Ford, '57 Chev or '69 Camaro if you really want to. And then there's modern Corvette chassis swaps, crate motors, the sky is the limit. When you're modding a car that everyone else has been modding for several decades there are plenty of options out there. The difficult part is knowing where to stop.
