Pontiac Grand Prix Forums : Grandprix

I own a 99 mustang v6 automatic with 65K. I am wanting to get back into a grand prix.. I have a guy with a 2000 grand prix GT, v6 with 135k on it. Automatic with aftermarket DVD player and sub woofers and the whole nine yards with audio. He wants to do a title for title even trade. Is this a good deal or am I getting screwed. My car KBB and NADA is 4500 and his is about 3200, so it's a lesser car for the kbb. Also his car has the check engine light on and the srs air bag light on?" Is this a major issue? Worse case scenario are we looking at a bad O2 sensor and maybe a srs airbag reset or something horribly wrong with the car. I really like the pontiac he has...it has a sunroof also which my daughter wants badly in my next car. He also has an aftermarket alarm system on it. It is in good shape red in color. Chrome wheels looks really nice. What do you all think is it worth the trade or should I stick with the mustang? Please let me know by tomorrow.
