It wasn't stock car racing, but do you remember the Mobilgas Economy Run each year? It supposedly was run with "stock" autos bought at various dealers around the country, but the auto companies eventually figured how to plant the cars they wanted. Back in the day it was a big deal and featured in all the automotive magazines as well as the national press. When I was around the track there was a married couple who worked for Simpson Safety Equipment, but also worked for NASCAR checking the contingency sponsor decals on all cars. I remember that both Bill & Nikki had driven in the Mobilgas Economy Runs and it was interesting to hear their stories. If it could ever be policed properly (which it probably couldn't) seems like this would be a great time to have those economy runs again, what with gas prices approaching coffee prices these days.
