Like I said in your other thread, I think it's great you want to do something like that for your dad . You had mentioned too you wanted to spend 6-8000. Here is an e-bay link for old camaros. It will give you an idea what you can get for that price range. Nothing had a buy it now that low, but if you skim it it may help.

To bad he doesn't want a 55 Chevy. Theres one for $4,500 around the corner from our house. But I will keep an eye out for you. Maybe try the Classic Car Trader also.
