Personally (or 'IMO'), I think they're great. As good as supercars are now, I can't help but feel (as repeated as this is), that they're held back by emissions regulations, road legality issues, marketability in the 'luxury sector' and so on and so forth. In my opinion of what a supercar should be, these restrictions detract from the essence of what a supercar is. I am afraid, having driven a couple of very powerful cars - albeit nothing in the league of Enzo at al, that I am not counting fully controllable traction control and other driver aids in the list of restrictions.
When cars that define 'supercar' in their era are as rare as the the truly elite that always fulfil those difficult to define criteria usually are; it's easy to see them as a piece of history that should be preserved in its original state. Especially when you consider the speactacular value of rare classic cars now (real Lamborghini Miura that's a 'fake' SV - £180,000). Cars like the Enzo, MC12, McLaren F1 (although that's probably an exception to the yet to be explained opinion), Bugatti EB110. Even lower down the scale in F430, 360, Gallardo, 575 territory, the majority of people who buy those will be far too concerned with residual value to consider 'unleashing their car's potential'.
Companies like Edo and Novetec are turning the lower end stuff into the hand built, uncompromised masterpieces they should be, and stuff like the MC12 into the car that could never come off a production line in 2005 - but (from an engineering point of view) could have easily done so.
What do ya reckon - abuse of heritage, realising of nostalgic dream or flippin excellent?
