We purchased a "mako Cat" from South Africa 18 months ago. Correct me if I am wrong but I think it is the same as a Zap Cat but you cannot race it in the UK as it is not inline with their requirements or "Brand".
It's only been used half a dozen times and is excellent condition but no trailer. A real gift at £1500.00 plus vat in white.
