Reminds me of the Corvette guys that were trying to trademark "Survivor" to extort $ from others. NSS - like Survivor - is a general term used publicly, and therefore I'd think pretty much impossible to actually register or trademark. That said, for cars that are period-correct in appearance, I like Ron's VSS term: while "nostalgia" is a term we're used to, "vintage" better implies that the cars are an accurate portrayal of the period in which they ran.
