Definately a parma. Same battery holder and rear end as my Street rod. Mongrel to get it to go straight as the fixed rear just bounces when it goes over a bump.
A mate of mine had a Sand Scorcher and a Holiday Buggy. I remember seeing the original tamiya Ralt and BMW F2 cars at the big toyshop near my home. This would have to have been back in about 1982/83.
