To get every cop car, go to the "User Name" Menu. Type in "NFS PD". You will hear a noise. The noise sounds like when you purchase a car from the Tournament or the Special Events. When you pick a cop car in Hot Pursuit mode, notice there is a new cop car. It's a Lamborghini Diablo SV with a diffrent paint job on it. Same with the BMW M5. And you also get to be any cop, even the International kinds when your in USA or Canada!!!
