Thats alot of money for a car that needs restored or your going to redo it.Buy 1 already done. JMO
And that's the other side of the coin. I agree, no way I'd pay that much for a Z in that kind of shape when there are nice driver quality Z's occasionally forsale in the $50k range. Paying $30k for one that needs completely gutted and redone and spending at least another $30k to do it right (likely more if you want it 100% correct), I think you can get into one in much better shape that's nearly done for less money if you're patient and willing to travel.
Even if I weren't planning to restore, and I do enjoy driving them in this condition, I still have a hard time spending that kind of $$ for something they made 20,302 of. Apparently the reserve is higher than $30k, so the seller is dreaming in my opinion, it's already more than all the money the car will bring in that shape (IMO), if I were him I'd take that $30k bid and run, lol.
