Hi I have this model, I find it very good on long journeys. I don't drive regularly on motorways but when I have it's been faultless got up to 55.4mpg on a run up to Yorkshire from Essex driving at normal speeds.
Noise:- not intrusive . but this will really depend on the tyres fitted.
Comfort:- not a car I feel the need to keep stopping in. none stop from North Norfolk back to Essex with ease.
Overtaking:- I have the 160bhp engine its perfect for motorway speeds, it's not a racing car obviously but easily got past the middle lane when needed.
