Talked to both Mugen and Shepherd at the Nurnberg fair, they are do not intend to start up production...
My good friend Luc build a 235 from a 200mm, put tremendous much effort in it, looked great, but the original chassis is not long enough.
shorter wheelbase: very nervous car.
Somebody in Australia did the same with a bit more luck, car was very driveable( have some pics if anybody is interested)
Somebody in germany won a race with a modified 200mm, but the car has been tested at Serpent HQ, and they found no real benefit in his creation.
But dear parts?
The 835 is one of the cheapest cars at the moment I believe.
And let us not forget: the easyest car to set up.( no choise between front diff/fixed/oneway, rollcenters and anything else a beginner messes up with)
I do not really believe a totally new car from one brand only would revive the class, but that is my humble opinion.
Some competion in brands, would more likely do the trick, so Palmaris go for it!!
