Our Cavalier has been very reliable and inexpensive to own. The only significant repair we have had to make, beyond routine maintenance, was the replacement of the fuel pump at about 80,000 miles. Even though I now work for a new car dealership of another make of cars, I have to say that our Cavalier was a good purchase for us.
Our favorite features are the low cost to own and drive and the reliability.
You'd think after driving this car for 116,000 miles that I could think of more suggestions. The only thing that really comes to mind is: Make the fuel pump less expensive to replace.
