I think here in the UK were quite lucky in that we only have to pass an MOT test... Wr dont have restrictions as to keeping our vehicles Manufacturer approved...once type approved by the Ministry we are free to do most things, within safety guidelines...hence the upsidr of a great kit car industry and the not so great rude boy bodge and ruin industry..within certain limits we have to record certain changes on our V5...engine change, colour change, use of vehicle change...but anythin else were pretty free. This enables us..or more specific in this case Dave to push beyond production limits to test theories and limits far beyond what would be considered by the,manufacturer to be viable and suitable for the average owner.. And as a result we have a road going car kicking out power equivalent to the factory race cars but achieving what they never did...road drivability for the public..a one off product that if say ten years ago had been financed by the factory, could well have secured the future production of the Esprit as a ground breaking serious contender against todays modern eurobox performance cars.. Appologies if that was a bit off topic! Its a bit hard to appreciate Daves Esprit over pictures, text and imagination...the devil truely is in the detail...
