I'm thinking about buying a 2007 Pontiac Grand Prix Base V6 3.8. I wanted to make sure of something before I buy it. Since gm stopped making Grand Prix'* in 2008, will I still be able to find parts for it? Thanks

I am still getting some factory parts on my 97 Park ave. Upper rad hose for instance..
The good news is that Rockauto has lots of aftermarket parts available which many cross over between gm models.
I say if you like the car go for it and worry about parts later. That is what I did on the ole PA.

Ok, I will check it out and go for it. Thanks, Soft Ride

You are Welcome.
I am not sure where you live, however many junk yards are often a good source for low cost original parts as well.
You will find the 3.8 engines reliable and long life, just keep the oil & filter changed every 3500 miles, that is what I do anyways.

For a base Grand Prix, you'll be fine. Plenty of them in the junkyards if ya ever need body panels or other larger components. There'* also enough of them on the road for all the common stuff to be sold in the aftermarket.
