What is the average life span for a Pontiac grand prix GT?

Answer 1

I bought a '04 Grand Prix GT in 2008 with 80k miles on it. I've kept it well maintained and currently (July 2012) have 145k on it. I can't think of any real problems it has had. I've kept oil replaced on it, typically with high mileage oil, replaced tires, rear brakes (requiring a special tool I borrowed from autozone).

Thinking about it, I've also replaced the vent fan, and a plastic elbow that leaked antifreeze. About 5k ago, my radio display went dark so I can't see what station I'm on or anything.

It does run a little warm, so I flushed the radiator and replaced the thermostat--no effect. It started leaking antifreeze around a little over 110k, so I replaced the water pump.

I consider all these things, however, practically trivial and of little cost. Big things (engine, transmission, etc.) all seem to run fine. I trusted it on a 3,000 mile road trip a couple months ago and will be making the same trip in this September. I drove the first 1500 miles straight with only a few short stops... never a hint of a hiccup. Returning I got tired and broke the 1500 miles into two days. :)
