I think you need to hire a certified appraiser from just what you have said. I don't mean an insurance value appraiser, I mean one that will use comps to come to a fair market value. From what you have said I think the car is waaay over priced because I have too little facts to even take an uneducated guess. Then there is the drivabilty issue. If it has to be a trailer queen because of what it is then it isn't any fun either. If I am going to have to do a $50K+ restoration on it then I can't enjoy it like I can a $10K driver restoration. I have owned some of the trailer queen cars and in months I got rid of them just because they were no fun. I didn't buy them to flip and basically traded $$$$ if not loose on them.
