http://en.wikipedia.org/wiki/Panther_Solo

The Solo 2 used the Ford Cosworth 2.0 L (1993 cc) engine with a Ferguson four wheel drive system modified by Panther. It is not known exactly how many vehicles were built (however it was between 12 and 25), as sometimes Panther would change the chassis number of prototype cars. All but three Solos were sold to the public, two were destroyed, and one is still owned by the then owner of Panther.
The body of the Solo 2 was primarily aluminium honeycomb sandwiched between carbon fibre, and was both designed and constructed by March Engineering.
