Sister Car

Back in the 70s and 80s car companies put out almost identical models through other small brands like Chevy put out the Monza and its sister car was the Pontiac Sunbird as well as in the 80s Ford Mustang had a sister car called the Mercury Capri Even the Chevy Chevette had a sister car called the Pontiac T1000. basically the same car with some minor trim and front end differences but basically the same car.

Did you see that little Chevy Chevette drive by, oh wait it was its sister car the Pontiac T1000 my mistake.
