I think a "running resto" is the way to go if possible. The holding value is the good part. My Harley was the same way. I sold it for exactly what I paid so it was basically like renting it for 5 years and all I had to cover was gas, property taxes and maintenance.
As far as my search, my head is spinning. I think I may just pull back for a bit. The SC bird I posted in my new thread "My FGF Search" is 9.5K but I'm just having a hard time pulling the trigger without seeing it in person or at least having someone check it out. I really have no idea what I'm looking at being so new to this. If I hired an appraiser, I still wouldn't know if the info he gave me equated to the price. The exterior looks done aside from badges.
Having bought one car like that, my advice is, NO, dont.
