Hey Pat, check out the magazine Grassroots Motorsports. Geared towards autocross / amateur racers / HPDE / track day crowd. Not mega dollar supercar stuff, but things the average joe could actually afford / use. Lots of resources to be found in their advertising, too.
You should be able to find it at Borders or Barnes and Noble.
Great magazine... the writers / editors own and MINI and have used it as a "project" car. There have been a few articles about MINI stuff in the past.
