just to throw my 2 cents in..
most young people drive the V6's (including yours truly) because they cant afford a GT or especially a Cobra. GT's cost more than 2k over the V6's and much less then that, for an 16, 17, or 18 year old guy, the insurance is a killer if they pay it them selves like i do. also, if they have smart responsible parents, they'd probably shit a brick if i came home with a GT or Cobra. but those are just my thoughts..
