You will find help with pretty much anything you need to know about a Grand Prix on this forum. The search function will be your biggest help.
Most of my questions have been answered many times over by people with waaay more knowledge and experience than I.
You will probably have to replace the upper and lower intake gaskets to keep the coolant from leaking. Might as well replace the coolant elbows as well and do the typical tune up stuff. Replace ALL fluids, fuel filter, air filter, pcv valve, seafoam it, injector cleaner, etc.
The only real weak spot on these cars, besides crappy gaskets, is the transmission. Make sure there is no hesitation or slipping in the gears. Check for play in the super charger snout and listen for any of the typical rattles and ticks that mean JUNK!
For the price you are paying it sounds like it may need quite a bit of work to certify. You usually get what you pay for.
I am from Newfoundland, Norris Arm, myself and I miss home dearly. Do whatever it takes to stay there and make a good living. Once you leave it is hard to get back. Good luck with the GTP.
