Should I buy a 2004 Grand Prix with high mileage?

I'm going into my senior year of high school and I need a new car pretty soon. Definitely before I go to college. I have a 1999 Grand AM with over 180,000 miles on it and it's just been a headache to drive. I think the previous owners were pretty rough on it. I was thinking of getting a white 2004 Grand Prix GT2 with 125,000 miles on it. It really want a newer style Grand Prix and that one is about all I can afford. I was just wondering if anyone has this car and if it's dependable, even with high mileage? Or should I just get a cheaper car with less miles? Thanks
