Head gasket blew two weeks ago at 147,000.
Catalytic Converter went out at 135,000.
The starter went at 130,000.
I have never seen a mechanic's face light up like it does when I say the words "Quad Four" to him. Each one just smiles and shakes his head and says "It could have been a great engine if GM would have finished it."
I had the head gasket go out a couple of weeks ago and can't even find a mechanic that will warranty a fix for any mileage.
Seats are fine for short rides, but we went on a road trip to Myrtle Beach last winter (500 mile drive) and each time we got out for gas or food our backs killed.
When you buy a car with that mileage, expect to replace stuff like the head gasket and such. Used cars aren't maintenance-free, and some people don't seem to realize that.
