The in-game pre-war company called "Chryslus Motors" is a reference to the real-world company Chrysler Motors. They produce two car models; The Corvega and Highwayman.
The Corvega brandname is a combination of two Chevrolet cars, the Corvair and the Vega.

The Highwayman is likely another nod to the post-apocalyptic Mad Max movies. The Chosen One from Fallout 2 can obtain a drivable Highwayman, with a blower sticking out of the car's hood, and was originally going to have two-fuel tanks in the trunk, much like Mad Max's V8 Interceptor from Mad Max 2: The Road Warrior.
