Well this thread certainly took a turn for the worst :lol: I've never seen anyone driving like that before but it might be something you'll need to sort otherwise you'll end up pulling/buggering up some sort of muscle which'll hurt like a bitch!
As for the Twingo not being a long distance cruiser... When I first got the 133 I had to drive up to Inverness for work training which is a 3 hour drive each way and it's fair to say after each journey I was deaf, had a sore arse and leg and my back felt funny :?
