Actually, if it's a complete car for $300, you can easily part it out for far more than that, if it turns out to be un-rebuildable. Not that I'd recommend scrapping yet another PV!

However, if this car has most of it's bits and pieces, you may find a bare body shell for sale (eBay?) cheaply enough to afford to put the two cars together so as to have a pretty nice one.

For a perspective on price; I paid $4,100 for my '64 PV544 (on eBay) and I've been winning trophies at car show with it, having done nothing visible but to detail it out.

The mechanical stuff you can't see, however, goes on forever!

I will say that so far (knock wood!) my little car has never let me down out on the road!
