My parents bought a 1991 Cavalier RS 2- door coupe 3-speed automatic a few years back and when I got my license, I was able to take it over. It's been a very reliable car, with only normal maintenance, like brakes. The only other issue was a sway bar link. It might not be the fastest car out there, but it's extremely reliable and gets from A to B with no problems. I even hit a deer and the car didn't get damaged at all.
The interior design, steering wheel, and wing style.
Too boxy on the exterior design, a little more power would be nice (95 hp stock)
