There are probably millions of Pinewood Derby cars collecting dust in boxes and attics all over North America. Here are a couple I've come across...

Pinewood Derby Cars

Basic body and paint, circa 1972.
More elaborate body and paint, circa 1974. This kit came with better wheels.
Hatchet job, mid-90s. Rescued from neighbor's trash.
The "Shark" ultra-fast concept, circa 2003. Never completed.
