But seriously, at this point any cash puts you ahead RIGHT NOW. In most circumstances, a finished car will sell quicker than a garage full of new parts. (however, there IS someone looking for a partially-completed Cobra for sale

Now, if you were to pay someone to finish the car for, say, $5,000, (estimated) and turn around and sell it for, say, $40,000, you would recoup more of your already-invested money. Unfortunately, things like this are a crapshoot. Depending on how fast you want to sell, determines the price you will get for the car. Start high and, depending on how soon you want to sell, drop your price accordingly. I have no idea how much a partially - completed Cobra is worth, but Double Venom would probably have a good idea what it is worth.
