been watching prices on 240zs escalating fast with the the nice ones going for $20 / 40k, it's crazy but that is the reality of it!
I've seen non running project cars going for $5 / 8k
260, 280, 300zx are going for less but not by a bunch! At an auction last week a
1996 limited edition 300zx tt w/6,000 mi. Sold for $54,000
Tr6 pristine examples can be had for $20/30k
Go to bringatrailer.com and you can see examples of both TR6s & Zs
