I have a 98 Cavalier that my wife got from a friend for around 800 bucks. It was wrecked and repaired (hence the price) and had 60k miles on it with the interior completely clean and a good motor in it. The only problem was, it was three colors on the front - red fender, primer hood and green bumper (the rest of the car is teal).
We went the $300 paint job route through Maaco and while it's obviously not the top of the line, it certainly did the job. I will tell you that for the price, you will sort of get what you pay for. There are a couple of blemishes in the paint, but literally only a couple.
Also, because we take this thing through a lot of different areas of the state, we get rocks chipping away at the paint, but this may be different for you depending on where you live.
Is it perfect? No. But for the price, it's a good option if you're wanting a better looking car. I have no regrets about it. I'd rather be driving a car that is one color.
