I had one of those COX Baja Buggies, for all of about a day or two. Me and my brother tried to start it on Christmas day, cold weather. Wore out the pull string. Took it back to KMart for a refund.

I remember the Testors airplanes with a McCoy .049 engine. They were built with the forward air intake and the timed cankshaft. Never did have the power of the Cox.
