Don't get your hopes up for a manufacturer to sponsor or run an national model car contest as it's just not going to happen. The modeling "boom" of the 60's is long gone. There were more builders "back in the day" than today. Now most of the builders are 40+ years old. The hobby business is a far cry from what it used to be and today it is a bad business venture. Many and I do mean many hobby shops from the 60's & 70's are long gone and the ones that are surviving are big into R/C because that's where the MONEY is! In the 50's, 60's, & 70's there were many "combo" businesses, like a camera store/ hobby shop, a Schwinn bicycle dealer/ hobby shop, pet store/hobby shop, confectionary store/ hobby shop,etc.. Manufacturers are not making tons of money on plastic model kits and are not going to use a contest to promote their business as all the model builders are fully aware of who makes model kits today. They don't have to advertise today like they did back in the 60's. Take your rose colored glasses off because a national model car contest put on or sponsored by a kit manufacturer is a far fetched idea.
