I just checked at Rockauto and an Airtex timing kit with water pump is listed at $68.79. My estimator program is at work, but I can't see the job taking more than 4 hours at a shop. If you supplied the part from Rockauto to a shop with a $100 an hour shop rate, even with taxes and fees you shouldn't exceed $550 total. The $800 you quoted in another post seems excessive. If you can't do the work yourself, perhaps a friend or co-worker could do it for you, or maybe you need to find a different shop than the one you are using. They did you no favours by not selling you a pump last time. As for the GM lifetime warranty on the ACDelco pump, it would cover the part, not the labour to install it which is the biggest portion of the cost. As for selling the car, how much of the $3000 you spent last year was for routine maintenance and how much was for repairs? Is the shop you are using competent with these little cars? Were all the "repairs" legitimate? With a little care, these cars are quite reliable.
