You're right there, you don't see many Twingos in general let alone some of the rarer models. Funny thing was I saw another Twingo Gordini down near Bristol which is where we were headed. Only the 2nd one of those I've seen on the road and that's in totally different areas.
I couldn't work out if your Twingo was a 133 or not as with the black and white look at a glance it looks very similar. Looked good though fella, where were you off too at speed? You could see why we get 45mpg+ out of the 133, 65mph all the way! lol
