They looked cool though!
2 years ago I helped fix up a friends junky 60's Chevy Van, it was the Scooby Doo Mystery Van version with the front seats above the front wheels and just one thin layer of sheet metal in front of your legs and a big pane of glass on up! Felt very vulnerable when riding in that thing!
Very little of the original plastics and vinyl parts survived - dried out and cracked.
New plastic parts outgas and a new car's plastic interior will smell like the factory for a while .... phew! I think the inside of my windshield gets coated with something emitted from the plastics.
Safety tip. Never stand downwind of a car or truck cab on fire. The smoke from the burning plastics is very toxic!
