If it helps you compare, best price I got was £16,813 for
RenaultSport Clio 200 (FF)
Cup chassis (inc. standard 'cup' anthracite wheels)
Glacier White
Fixed cornering lights
Folding door mirrors
RenaultSport Monitor pack (inc. bluetooth)
£1,400 more than your quote, but if you dumped the mirrors, cornering lights and monitor from mine, it'd pretty much cover the cost of Recaro seats, and that's for a full fat rather than a cup so obviously includes full climate and all the other bells and whistles that are associated with the FF.
If it was a cup I was looking at, I'm pretty sure it would come in less than your quote.
