never had a problem with reliability or things with any of my cars *knock on wood*, but least favorite car would probably be my first, 1996 chevy blazer. Nice little suv, wasnt good on gas with my driving style, all around it was a good vehicle though..
worst for problems was probably my 240sx, parasitic drain, had to start it each day..but other than that she was a gem. Ive had a few jeeps before and my last one the doors leaked when it rained but floor was rhino lined and the rust hole in the passenger floor was a good drain so i didnt really consider it a problem..
