I've mentioned before that Sears used several suppliers to fill orders for bodies, Here is an interesting spin on the story. This Spatz currently on ebay obviously was ordered through Sears - but here's the interesting twist. The Manual with the car is the one Terra Buggy supplied with their bodies. Sears must have supplied Terra Buggy literature to Spatz to include in the kit. This body has the Spatz emblem instead of the Sears sticker, but the book is a dead givaway to where this one was purchased !
