Have not had the car long!! Purchased it for $800.00 and it is the best $800.00 spent.
I took it on a 3.5 hour trip the first day I got it. (I also have a 2007 Grand Prix - I left at home that day LOL).
I have given it an oil change, tune up and changed the valve cover gaskets. Just to make it run a little smoother. However it ran just fine the way it was.
My wife loves the car and says people look at it when she is stopped at the light. It is a classy lady for sure.
One the road she drives so smooth you might go to sleep!! If you find one, buy it!!!
Changing the valve cover gaskets makes it "run a little smoother"?
On what obscure automotive mechanics theory are you basing that assertion?
