AAAHHHH a man after my own heart. There are several individuals and or compaines that either make salt flat accessories for models or just models them selves. AMT did a couple the attempt 1 from Mickey Thompson, also the challenger 1, also they did a 37 chevy that was called the salt flat racer, and they also did a studebaker that was called the salty dog.
If you are interested email me off board and I can direct you to lots of information about these as well as shows, contests, etc.
If you are interested in just normal every day cars old and new, a good friend of mine is resin casting models of almost every type of car, he likes the station wagons, but he has done many, many, many, others. From 4dr posts to limos, to just about anything produced in real life.
Talk to you later
