I use to drive a ford ranger. I was always jealous my girlfriend had a Grand Am GT. It was comfy, decent styling, and to what I thought "fast". Then I got my GTP and what a worlds difference. I always hate driving her car cause it seems so slow and no responsive. I prolly get the same MPG as her just cause she has a lead foot. I average around 21 mpg mix highway/town with a decent light foot. On a trip, at around 80mph i averaged 27-28mpg, and at around 65-70 i got around 30 or more mpg. This car gets pretty good highway mileage, driving down a road that goes across several towns thats 45-50mph, i can get around 30mpg. But then when i want that lil extra power or need to get ahead of a car, its not problem. GTP is deff worth it. I wouldn't bother with a non SC car tbh. Too slow for my styling and they get around same MPG tbh. Just when you get on that SC that it starts going down.
