^ My wife's aveo has 105,000 miles and I think it has the stock belt (bought used). It is a 2004. I'm changing the belt this or next weekend to be safe, the 4 peice kit grom gates (belt, idler, tensioner, and water pump) and a new serpentine belt I think only cost me like $100-$150. I'll probably spend the whole saturday working on the car. My valve cover gaskets around the plugs also leak...
