Bought it sight unseen. Photos were just OK, but I spoke with the seller (a broker) and he gave me a good description, and his feedback rating of 100% over several years bolstered my confidence.
I bought my C/S the same way - thru E-bay, sight unseen. When it was delivered, it knocked my socks off as far as condition & documentation. The previous owner had done a first class restoration (all correct) and included a filing box with reciepts, logbook of work accomplished, and a gazillion photos of the process. Even a photo album. Needless to say, I was ecstatic. I've added dual GT exhaust, SS wheels, and just tweaked a few things.
The convertable should be here next week. I'll be all over it checking things out. Maybe add P/B, but keep the car original. Happy Days!!
