This car has been for sale for a good long while. The asking price is way high for a project in this state. All the parts "MAY" be there, but that's obviously open to question. Then there's the labor to put it all back together. If you were to have them do it you're looking at another $30k at least and then there's the other bits and pieces. Yes it looks to be pretty well restored for as far as they got, but the engine compartment didn't look like it was stripped and redone. Maybe a do it yourselfer would take it on, but when you can buy a very decent car that's all there and you know what you're getting for around this price. It's been on the market for more than 6 months and no takers so that tells you that it's not a bargain. In this case it's more likely that the seller has added up all that he has in it and wants to get close to well on the sale and that's not likely.
I'd be interested in seeing how much CSI would quote as a fixed price to do the work and deliver it done. That would be interesting and puts the risk on them. My guess is they're going to want the lump up front and then an open tab to do the work and that's going to be a very pricey proposition.
