My idea was to engineer the body and chassis to be bigger tyres and higher clearance than anything else on the market but built to be legal to register at that height. I figure not many people would buy them, but even just 5 or 10 a year still makes a viable enterprise. Also selling them as incomplete kit, without driveline installed, just as a rolling body chassis, for 35k etc. And the buyer can get a driveline, lights and brakelines fitted and seek kit car approval themselves.

I reckon just making the rolling chassis would cost me 10 to 15k and they would possibly sell as a kit for 30 to 35k in that rolling chassis stage.

The restrictions on lifting standard 4x4s IMO would enhanc the viability of being ableto buy something like this thats built and approved with the high lift + big tyres set up.

To do that would haveto keep the roof level low and centre of gravity low, and be a floorpan monocorque body type chassis, rather than body on frame that makes them top heavy.
