Hi Stu and thanks
Apart from a higher HP motor, better ergonomics, better handling (stock V's lowered)
IRS V's live axle and better tyres - yeah your right slightly up market.
I was going through some paper work from previous owner and car has been chipped - thought related to paint work but think it's engine management.
Had what I thought was GMH parts under the bonnet but checked and it's the name for the big mouth cold air induction.
Wonder what else I am going to learn
Cheers Vincenzo
