What is missing today from too many normal cars and kit cars, and what the M3W has oudles of, is "character".
The S&S engine may not be the smoothest in the world or the most reliable, but it suits the character of the car.
Another beauty of the M3W is the absence of GRP and the thought that it has come out of a mould.
This "character" to which I refer is something that is almost intangible and possibly appreciated more by us "older generation" who cut our teeth on vehicles that did not have the numbness of most cars of today.
To alter the M3W in any major way (apart from improving it's reliability) would only detract from this "character".
