My Girlfriend had a 2000 Cavalier ("Little Red Rocket") when we started dating. Was reliable enough, 2.2l automatic. I did quite a bit of maintenance on it, she wasn't the best at keeping up with things when we first met. It got a water pump, valve cover gasket, both CV axle, and brakes while she had it, nothing major. I also replaced and/or epoxied back together practically the entire dash, which only developed more cracks.
Interior generally sucked, cheap as cheap gets, seats weren't uncomfortable, but I drive a Volvo, so seriously I'm spoiled. Here's was a 2 door, one grown normal sized person could fit in the back seat comfortably-ish if you sat kind of sideways.
We actually took a few road trips in that car, mileage wasn't great considering what it was, upper 20s were the normal average, if it was all highway you could expect to brake 30 but just.
Another peculiarity, she had an car audio shop put a CD player in it to replace the factory tape deck/radio, and they actually put the factory radio in the trunk, and ran a wiring harness from it back to the dash and aftermarket CD player. Apparently the door chime, and seems like something else (fuzzy memory) don't work without the factory radio, chime plays over the car speakers?
We sold the Cavalier a couple years after she finished grad school. I detailed it, touched up all the paint chips, put a good coat of wax on it, and sold it in '09 for $1700 with ~135K miles, decent rubber, a tear in the console lid, a softball dent in the hood, and a listed $2K OBO.
