Touring Cars Challenge -Further consideration
I want to keep the Modern Group essentially a "3d chassis " construction class, based on Scalex, SCX or Ninco bodies, so there will not be any Slot it models permitted in this.
But the Over 2.0 Litre group will be an "Open Class" and with a  pre 1990 era would allow at least for the Slot it Mercedes 190E and the Nissan Skyline GT-R to run against the Muscle cars. The Slot it Alfa 155, Merc C Class and the Calibra would not be permitted as they arrived to late for them to be considered within this era group. 
But Ninco made both the Calibre and Alfa 155 which would be allowed in the Modern Group fitted with 3d chassis.
The under 2.0 litre Group would permit the use of Revoslots but probably not as a separate Class (as there would not be very many) not made up my mind as to whether this should be a controlled or open Group, perhaps we might get another Slot it car similar to the Datsun by then ?
