White SUV visible in opening scene: in the opening convertible scene, just after picking up the hitchhiker and around the point where Duke narrates "...when my attorney starts screaming about bats..." in the closeup shot of the hitchhiker. Just before the shot changes, an out-of-place white SUV can be spotted the far right of the screen behind the hitchhiker, parked along the desert highway.

While driving down the Vegas strip in the convertible on the way to the Debbie Reynolds concert, they pass Binion's Horseshoe Hotel and Casino twice. However, the scenes outside of the car are not meant to be realistic. It shows lots of casinos that are not in order, but this is from the mind of a drugged out driver - the car itself is floating in air the whole time.
In a few shots taking place in the Chevy's interior, you can see the car has white vinyl door panels from a 1973 or 74 Impala (or Caprice convertible), while the main "Red Shark" is actually a 1971 Impala convertible. The Impala had slightly different door panels for 71/72 than the 73/74, but was essentially the same car overall. Apparently another car was fixed up for use in the movie as a backup or secondary vehicle and used for some shots from the inside.
The California Highway Patrol squad car used to chase Duke was a 1974 Plymouth Satellite. The real California Highway Patrol used Dodge Polaras at the time. Additionally, the Federal Signal Corporation "AeroDynic" red and blue light bar on the roof of the police car was not invented until the 1980s and would not have existed in 1971.
