Bought my 2005 Aveo LS in October 2004 new. Now have 217,000 miles on it. Replaced timing belt, plugs and wires once. Only thing else I have done to the engine is change the valve cover gasket. I have always changed the oil every 3,000 miles or so. That is the key to keeping any motor going. I did have the transmission go out at 155,00 miles.
