Yes they do have all the "tools", but the main reason kits are not produced is licensing. It costs alot of cash to get the "rights" to a manufacturers product. Just an example of what goes on to produce a Nascar kit. The manufacturer(Ford,Chevy...) wants a cut, then the Nascar guys want their cut. And don't forget about the driver of said subject(Jimmy,Dale,Tony...) they get a cut. The kit without the licensing fee would cost the average model company about $9 ea. for a run of 5000 kits. Add all those costs and then another 20% for the hobby reseller.
