A z06 is DEF worth that to me.
But i just dont see paying 70k on one, if you can even get them at that price. I would buy an old skyline, IMO the older styles looked better.
I think its probably worth the 70k but not in my book.
The only upside to it is all the different setups you can have, the computer in that thing is nasty sick.
But thats just my take on it im sure you could argue your case too.

Exactly what im saying SUICIDAL they wont be available at that 70k price so to be more realistic it has to be put up against 100k dollar cars.
The zr1 is like 750whp, might be 750 at the crank but that will walk all over the GTR
