you know you drive a gp when you replace wheel bearings when you change your oil.
you know you drive a gp when your wipers dont go down, and you feel bad for the other gp drivers that you see with the same problem
you know you drive a GTP when you look at every gp you see on the road to know if its a gt or a gtp. (at least i do haha)
you know you drive a gp when you can beat all the ricers in town even when your tranny slips like its on ice every time you go WOT
