One of my mates has had hers for about 3 or 4 months now. 'Fast as f**k' is a SERIOUS overstatement. It has 100bhp, 25bhp more than the old 1.2 16v and it weighs a good load more, so it isn't much of a performance increase on her old 1.2 16v Extreme. Marginally better in gear, but again, the weight and longer gearing don't give it any help. It's economical though - but a hot hatch, or even a warm hatch, is certainly is not. Of course, may be much better in the lighter Twingo - I haven't tried it.
