I'm a long time grand prix owner (2001 GT) and I wanted to get some opinion on my next purchase.

I found a '07 Grand Prix GT that's been sitting on the dealer's lot for 4 years that looks like a good deal (real nice body mods, premium wheels, etc.) but I'm concerned about buying a car that has been sitting around that long (51 miles on it).

Does anyone have any experience doing something like this? Any thoughts on things I should look for (seals, hoses drying out, etc.)? I'm not necessarily concerned about right now, but the potential for problems when I get to 100k miles has me worried.

New around here so let me know if I'm not posting in the right spot.
