Hi Nick. the post previous to yours above says it really.
The new 1.4 engine is sweet and lively, I've got the Driver assist on Auto at the moment - will experiment with that later. Ride is definitely better than A1. The electric handbrake feels a bit odd at first and I've tried to operate it the wrong way at least once - you have to think of it as a handbrake and pull it up to engage (rather than as a button that you press to select, if you get my meaning). Other than that very comfortable, and, the fuel gauge hasn't moved from the half full mark with 100 or so miles so far.
Bigger car, similar performance, better economy, no change to insurance - seems like a winner.
