The Ford Mustang SSP, meaning it had the Special Service Package, made a living chasing Porsches from 1982 to 1993. Ford has offered a number of other cars with police packages since that time, but none have been Mustangs. But that's likely to be little consolation to speeders in a growing number of states. To be exact, the Missouri fleet welcomed 10 Mustang GTs that will be deployed for both routine duties and emergency response. However, since the performance of the Mustang GT is far from routine, drivers chosen for the Mustang program will need to pass an extra round of vehicle-operations training.
