1978 Chevy Monza with the miserable 2.5, bought in 1986. Thankfully, a 4-speed. That car nickeled and dimed me to death, which sucked on a Burger King paycheck. You name it...it broke at some point before I finally got to ditch it for a '86 Civic Si. A world of difference there.
Gotta comment on this....I had the 'next version' of this car, the '85 Skyhawk (the Cavalier et al replaced the Monza et al), and it gave me nothing but problems as well.
I traded mine on a 1986 Honda Civic (non-Si though) as well! LOL!
