In the titles of Starsky & Hutch, they were chasing some bad guys in their black limo. Jim Rockford only had to step outside his caravan and he’d be accosted by some thugs in suits and he’d be pushed into the back of a black limo. If you drove to any deserted land around Los Angeles in the late ’70s there’d be a black limo parked up with Mr Big sitting in the back and a briefcase full of money on the seat.
The LA police could have cut crime by 80% if they’d just run a check on all owners of black limos and arrested them. However instead of this there was usually a chase, if a regular sedan of the period handled badly, a big old Cadillac or Mercury would handle worse but the meathead hunched over the wheel would work miracles, or maybe it was just the second unit director.
