Who the heck buys a car without looking at it first? This says it all: ". My mistake for not looking at it, but i really trusted him. And was getting sick of loking(sic) for a Z. And was exactly what i wanted." Caveat Emptor! When you sell a car it's hard to point out every tiny little flaw. If you tried doing that, you'd never sell the damn thing. It's an old car and none of the things you listed are that serious or difficult to fix. Chalk this up as a learning experience.
