I'm with John on this one, the restored cars are becoming more pricy and the bone stock originals are bringing some good money. Remember the fellow that documented his S30 with the SR20 engine, all the suspension goodies from AZZC, super clean to begin with. He was asking $100K initially? Then there was Taz240Z.V-8, his car sold for 36K.
One of the problems is parts availability, (all prices are what I estimates) new tail lights if you can find them are around $800, clear front lenses $250, fender mirrors $350, door panels $800, interior plastics (available $450) straighten out a front and rear bumper and rechrome it $$$. I mean everything on these cars (NOS parts) are going through the roof due to little aftermarket support. I do appreciate you folks that are making parts, don't get me wrong.
It's not like a first gen Camaro, you can buy every part to include a body. That's crazy!
