Help!!

I have a 1999 Blazer with the 4.3L v6 and i am trying to sell it. But i need suggestions on what to get! I want to get something with plenty of power but i also need to get great gas mileage driving to college everyday... Any suggestions? I was looking at maybe a newer grand prix or something like that. i just need to get something very fast but very good gas mileage!

i would stick with the blazer or if that is not an option i would suggest getting a chevrolet beretta gt or a 300zx i have had good experiences with both (great mileage and decent power)
