Adventures in car buying

I bought a used car some time ago and the salesman told me he would detail this, fix that, repair that and as soon as I signed the dotted line all I got was an oil change and an car wash. The salesman told me that the issues I had addressed with the car were no longer his problem. General Manager told me the same thing. It seems once these slimeballs get you to sign you are no longer there problem and could careless about you. Car is great now but I had to pay out of pocket to get some of these issues fixed. Moral of story is get all promises in writing. Also if the car has a guarntee check to see what it covers. Make sure it covers Transmission and Engine to at least 90,000 miles.
