dream cars and project cars

lately, i have been trying to start a new hobby: building up my dream car. now, i want it to have a real classic look. so the first thing would be to get an old car which is in good condition, preferably without any serious rust problems. then i'd soup it up and make it a PIMP ride, babe. so, here's a short list of the cars i'm considering:
1. Datsun 240Z / 260Z (70's made)
2. Volvo 122S or 121(dating back to the 60's)
3. Toyota Celica Liftback Model (from the 70's)


but if you see any around, pls do ask if the owners are interested to sell and at what price. I am getting wet just thinking about the joy i'm gonna have at piecing the dream car together. update: here are the pics of the cars i am looking for. they are sexy and imagine them being PIMPED up. mannnnnn.... getting wet all over again! HELP ME HUNT FOR THEM, PLEASE!
imaspongy and i'm outtttttttttttttttttttttttttttttttttttttttttt.
