One more question. I have a 2003 grand prix gt with 77790 miles on it. I have a small oil leak. I need the oil pan gasket and rear main seal replaced. I can't do it and I might have someone who can do it for $1000. Otherwise a local shop would do it for $2000. I love my car, but I want to supercharge it. Besides the oil leak which is just minor right now, it is in very good shape. I have an aftermarket radio in and HID 6000K headlights. I think I'd get $5,000 if I sold it ($3000ish if I sold it to a dealer). I've thought about buying a 2006 grand prix gt supercharged. It's been tuned some already and in better shape than mine. 69K miles on it, black heated leather seats (bonus!) and it's silver (the color I want). It also has a winter and a summer set of wheels and tires. The guy is asking $10K for it. I know a s/c grand prix doesn't come up for sale often, at least the nice ones. I'm a college student so money is a bit tight. Would you recommend upgrading to the 06 grand prix, or should I keep my 03 grand prix and get a s/c with supporting mods and fix the oil leak later?
