I would decide more on the condition of the individual car and not on the designation,both cars are great but depending on what you want out of the vehicle ,if you plan on staying relativly stock and want performance look for a low mileage GTP if you are more of a do it yourself builder buy a GT cheaper and build what you want,so I'm saying deside what you want and buy it do'nt regret the model you chose later.Chico(pops)
