There are 2 versions of the 1.6 diesel, 75 hp and 92 hp - we have the latter. Noisewise, it's fine so far, no real difference to the petro,l version as far as I'm concerned. Performance is fine, acceleration in first gear seems quicker to be honest. Trip computer is showing average mpg at 42.8 at the moment, and rising slwoly - but it's all town driving no longer runs yet. Deals - there is the usual cash back offer, which always seems to be threatening to come to an end at the end of the particular month you enquire, and also the free in car DVD system at the moment.
