Lance Reventlow's Scarab Mk. I was one of the first American Specials and also the first Scarab. It used some of the best west coast talent and inspired many other similar cars. The Mk. I used a small-block Chevy V8 in an untypical space frame chassis which made it very quick.
Saw this in the GNRS coverage and went looking for more.
