I used to own/run/rebuild a kit Car in the UK - a Sylva Leader. Insurance was one of the things that attracted me to them as I could insure a 1600cc, 100bhp, two seat, roadster for signifficantly less (1/2 the cost) than a 1100cc, 55bhp 4 seater tin box (Fiesta). The engines we actually different version of the same design - the old Kent crossflow.
This was back in the late 80's. We had specialist insurance for kit cars, and the insurance brokers took the view that if you built the car yourself, then it would be likely, that you would look after it better and perhaps even assist with the repair if things went wrong. For a 22 year old budding racing driver, it was music to my ears. Ran it for 6 years, before getting into bikes.
Those Puris Eureka's were marketed as Nova's in the UK and were based on VW beetle chassis and running gear. There used to be one in my street - always felt it was a bit odd - the looks of a fire-breathing sports car and the sound of a vw beetle.....did not stack up! Unless the Purvis is an update on the original Nova theme - cant see a beetle engine under the back. But the rest looks exactly the same.
