I just sold my 03 Cavalier, it had 125,000 miles. I owned it for 18 months. I had problems with it leaking oil and had to replace the rear main seal, also recently the a/c unit went out in it which caused me to sell. but other than that it was reliable, always started and never left me on the side of the road.
cheap price, fuel economy was excellent.
interior design was the biggest flaw with this car, you would have to move any drink you had in the cupholders to change anything on the climate contol system.
