 We have had our Spectra for almost four years now and the only major problem we had it in for was the throttle position sensor.  Yeah, it took four return trips to the dealership (175 miles away, ouch!) but eventually the throttle body was replaced under warranty.  Honestly, if you follow routine service and don't treat it like a red-neck stepchild, you should get many years of good use out of it, just like any other car.
