I'm with XfbodyX. $1,500-$2,000 would be more realistic. A car that's sat idle for 25 or 30 years is going to need a new fuel system, battery, belts, hoses. all the fluids changed, entire brake system gone through and repaired/replaced, new tires, etc, etc, before it could even be driven. Then it's hard telling what problem could show up once it's drivable. All that, plus make, model, trim level, engine, body style and demand figures into the price. Also depends WHERE it was parked. Time does way more damage than miles do. Then there's the question of why it sat so long. Was there a mechaical reason they quit driving it or?
In the end though, a car, or anything else, is only worth what a buyer is willing to pay. All depends on how much a person wants it.
Short story. Way back in the early '80's I saw a 72 Barracuda advertised for $100. Seems the bypass hose blew and it died and wouldn't restart, and had been parked over a year. He couldn't figure out what was wrong. Me and a buddy went over to look at it and I handed the guy $100. He gave me keys and the title. We had brought a hose, coolant and a couple other parts along with a battery. Replaced the hose in the parking lot of the sellers apt. building. My buddy cranked it and I saw the coil arcing to the primary. Bolted on the coil we had with us and, it fired right up. It was less thanb20 minutes since the title changef hands. Just then ,the former owner walked out of the building. The look on his face, PRICELESS! Drove the car home.
