As said it's a cosmetic change which is a bit of a shame but I considered it more of a homage to the Gordini brand of old rather than a follow up. Also, I'm far more a fan of the Twingo 133 Gordini than the Clio 200 Gordini. There are a list of small hatches now with stripes and lairy styling, the Twingo can pull off the look because it's a tiny car. The Clio looks a little awkward all dressed up and if I'd been in the market for a Clio 200 I'd not have gone for the Gordini.
That said, on Twingo Gordini I have, the interior is a step above the poverty spec interior of a standard 133 and for me that made the difference. Also, the book price of a Twingo 133 Gordini is £14,500. My Mrs ordered a glacier white 133, with the black/white packs, panoramic roof and Cup chassis and the book prices ended up £100 more than mine.
As above, if you want all the toys in a car then the Gordini has everything chucked in. Full leather, climate control, MP3/Bluetooth stereo etc.
