lol thank hercman... I will see you someday to race you for mpg thing. I will keep you post.

I don't see nothing wrong with 200,000 or 300,000 miles on this car. Your dealership might be retard. It is pretty good car last longer. I would keep both GP forever to save me some money until whatever my future will be. I have 250,000 miles 1997 Oldmobile Cutlass Supreme. I sold it because I like GP look better than this. Oh my dad have 1985 Chevy Caprice (brand-new). It is very huge car. I love gas this car from rear bumper where plate is. He has it until 1997. 12 years and lot of mileage on this car. The engine was blew up.

Turbo on 3100 engine? That's new but I think turbo eat lot of gas? I would wait and see how my mpg doing first before I decide to swap them or not. My gas gauge hit orange mark tonight. It is turn "low fuel" light on. My gauge is fine but I bet I saved lot of gas after new exhaust installed. Tomorrow morning, I need fill her up and start reset trip to zero then start math thing when it is empty for other 2 weeks later. I'm looking forward that for what is real mpg.
