The Motion Models site is still up and growing all the time. He sells some very nice models. There used to be some models of the cars on there but I don't see any now. The only thing I see on the cars is "Motion Models is a wholly owned subsidiary of the famous Baldwin Motion Performance Group, which since 1957 has brought the automotive enthusiast special custom made high performance cars."
This is the site and the email and numbers listed on there;
