The Montegos were good on paper but not on the street. They were unliked by most Patrolman. A 429 V-8, Manuel steering, Manuel brakes, nose heavy, and one slipped through with a/c. There is a story where complete dash fell into the laps of two officers. So the LAPD ask Jack Webb not to use a Montego. You do see them as back ground and back up cars but never a hero car.
The CHP had problems with the Monterey’s. Good on paper but problems on the road. Like transmission cases cracking at the bell housing, breaking motor mounts, and wheel centers cracking around the lugs. They were the cheaper bid and only on year only cars for the LAPD and CHP.
