We have just swapped our MK1 1.4 jazz sport for a 2109 sport and if the cars fuel readout is accurate it seams very similar to our old car, it is just the grin on my face when driving it that has got wider.!
Pulling on to the motorway from the slip road is a lot better.
Like you we do not do many miles in the car but when we do it is mostly for longer runs as the wife takes the bus and I use a motorcycle for commuting.
