How to tell if it is a cup edition

Hi all,
A friend of mine is looking to buy a 133 and wants some advice on the cup edition.
I was under the impression if it was the cup edition then it had the 2 separate seats in the back not the bench...?
He is looking at a 2009 version of the 133 if this makes any difference.
Can anyone give advice on what to look out for that makes it a cup version.

Hi. The Twingo RS comes as three different versions. Non cup, 16" wheels are the usual indication and the rear shocks won`t have a purple dot on them. The purple dot denotes a cup chassis which obviously a non cup won`t have. It also has two individual rear seats, tinted rear glass, aircon etc. A full fat Twingo RS with cup chassis will have 17" wheels, purple dot on rear shocks, two individual seats in rear, tinted rear glass, aircon etc. The out and out Twingo RS Cup has 17"s, a bench seat in the rear, no aircon, no tinted rear glass etc but will have the purple dot. The Gordini and Silverstone are special editions but they have all the toys as you get with a full fat. If it`s a proper out and out cup you want, look for the bench seat in the back. You will find the door mirrors and badges will have changed from 2009 through to 2012 and bumper parts that were matt black change to piano black. Small changes but 2012 saw a major facelift and a trawl through this site will help you see the changes. Hope this helps!
