Well, hmm. I find 10 old cars for every single one that the owner will part with and most of them I can't afford anyway. If that is your ultimate disappointment you have a very dismal life ahead of you as a gearhead.
I found in east Texas that any car you could see from an alley or road was either "my daddy bought that new" or an Imona car (Imona fixer up someday)
If it could be bought someone already would have before you came along. That's the sad reality of old cars. But then I also believe that things happen like they are supposed to and you will find the right car/truck/motorcycle/boat whatever, exactly at the right time and it will be the right deal for you. Keep looking, the hunt is half the fun.
