Insurance Group - S Works

[mindgam3]

Is it 19? I've found that in a few magazines, but can't understand why when it has less/equal power to a type r and probably less of a "nickability" factor. Any ideas if this is a correct group?

And what sort of insurance percentage increase would I be getting compared to a Cooper S for a 21 year old?

I think at most its a group 17. I've had a few resonable quotes so I doubt its a group 20...
