Would there be a class for modified stock, or would that go into the scratch building section ?
If a modified stock is eligible I might want to field an entry 

I think with the numbers of entrants and cars we have at the moment it would not make sense for another separate class, although I would dearly love to introduce e a Truck class   but sadly at the moment I would probably be the only entrant.

But yes your entry would be welcome and the "modified stock" vehicle would be placed into either the Pro Class or the Scratch build class depending on the nature of its modification. My Jaguar I-Pace was actually a Scalextric stock body with a Mitoos chassis etc. I decided on the basis of the knowledge I had on the other Scratch build vehicles submitted, to place it into the Pro Class, as the Mitoos chassis was well capable of competing with the Avants and Scaleauto's. 
Mind you if its a Truck perhaps we could have a 2 vehicle class
