I hear what you are saying, but i stand by the claim that the Elise Motorsport was nothing that special from the road going version of the S1 Exige which spawned from it. Like i said it was basically a M3 CSL with some trick gear.
Grab any number of catalogues and you can turn your basic S1 Elise, the pick of the litter as they are a lot lighter then the S2 (the S2 have the same chassis/suspension, its an update of the bodywork and accessories hence the higher weight) into a car that looks like a Motorsport but blows the doors off it as there are off the shelf kits for Audi engine transplants, EVO engine transplants using Quaife boxes etc and the Honda engine transplants using Honda Boxes
Hell shop around Japanese workshops and there are some pretty crazy tuned up Elises running around which completely transform the appearance of a std S1 Elise. (pic below)
And all it takes to do the cosmetics is a $6000 bodykit which is mostly fibrelgass but part carbon. For full carbon it is a more expensive from memory and cant remember the price. Considering you can pick up S1 Elises for 35k i dont see them as being that different to an Evo 7 or R33 GTR after people have put mega suspension, carbon doors, big dollar engines and boxes in them...completely different ways of going quick.
So, sounds like you know all this already, but just because they have the "motorsport" model look of the S1 Exige doesnt mean they are anything special. They are only what they are because of the base model S1 Elise has so much potential.
If they have been built up then ok, but if they are the "1 of 15" factory GT2 or GT3 cars etc then ...
