I have a 2001 Olds Alero that I bought new and love it.
Ihave had the spark plugs replaced and there was a time that it was shorting out a wire or something that made it strand me, but we got that fixed under warranty.
My 'worst' car was probably my first car - a 1986 Ford Temp - I loved it b/c it was my first car tho.
The AC would fog up the windows and the horn busted. (those were the days in HS where horn was important ) My dad replaced it with an air horn that vibrated the dash when it blew. I scared the crap out of my uncle when he was riding with me once and I blew the horn and the whole car shook.
