Nowhere is the spirit of automotive irreverence more celebrated than at this now-nationwide series of on-track endurance races for cars costing less than $500, including all prep except safety items, brakes, and wheels/tires. The brainchild of journalist and Chief Perpetrator Jay Lamm, the LeMons 24 evolved from the Double 500, a 500-kilometer road rally for $500 cars, and fairly brims with hilariously absurd rules. Some races are real LeMans-style 24-straight-hour runs; others give breaks overnight. Silliness abounds, and as with the Plymouth-Dakar, don't get too attached to your car (or bring an over-$500 cheater). Midway through, the participants vote on one car that gets crushed on the spot.
