True, but it was at least made available again...for three months or so.
I suspect just about every current/modern racing subject is a tough sell, since each car has a unique set of markings and the cars change every year, and sometimes even during the year. Updates to the tooling would be needed every year, and I recall some complaints about the Monogram/Revell Pro Stock kits in the '90s containing the same old '80s chassis, engines, etc. I just don't think there's a profit to be made in kits like this, at least compared to a kit of a Sox & Martin '70 Hemi 'Cuda, which only comes in one version, and won't ever change.
I have to somewhat disagree with that, model companys have been doing race subjects for a very long time on race subjects that change body style/colors/sponsors, so I dont think thats a big issue.
If what you said was true, NASCAR kits would have not been done, they changed almost every year for a period of time when Revellogram was still producing the kits
