Tucson and Oro Valley police are now using siler suped up Ford Mustangs. The cars are unmarked, and you’d never guess they are cops. Most I have seen are parked on small side roads just off Oracle Rd and are using radar and laser to get people that are speeding in the construction zones on North Oracle, between Desert Sky and Ina Road. Use caution when going through this area, as the speed limit changes and the cops are waiting for you.
