I bought a '71 on eBay last year for ~$45k. (I don't remember the exact price as that was determined by people bidding up under my max bid, but it was right around $45,000)
It had been parked in a garage for 25 years, engine would not turn, almost all original but for common 80's era engine mods - exhaust, carb, intake. Minor rust in rockers and a spot in the driver side door jamb. Original wheels, but I can tell they have been repaired. Paint ok from 20 feet but it needs new paint.. black sprayed over original bronze. I think the only part missing was the DeTomaso badge on the rear.
(Marvel Mystery Oil and rocking the car in 4th gear got the engine to turn.)
The people I was bidding against were bad at eBay though. It might have gone higher if they had known how to use it correctly. The seller told me they were Europeans and wanted to export the car. He was rooting for me to keep it here.
