I'm certain that the 165 is available in both Sport and Dynamic trim.

Of course the Sport is better looks wise and most have plenty of extras to match up with the Dynamic's. Be aware of the harder ride though in the Sport.
I love mine and wouldn't change it for anything, certainly not for now anyway. In terms of value for money I think they are unbeatable.
With careful driving I get about 50-53mpg on my 50 mile (round trip) daily commute to work in moderate traffic. 75% of which is Dual Carriageway. When I drive a bit more enthusiastically, which you need to do every so often, it will return about 46-48mpg.
On a long journey you can easily achieve 55mpg (indicated).
650 miles is easily achievable from a tank.
The 2.0 certainly seems to be the most refined and mechanically sound. It may not return as good MPG as the smaller 1.6 (which I had in a MiTo) however it does cruise better IMO.
This car is at its best at motorway speed and really isn't ideal if you are going to be driving around town most of the time or doing short journeys.
Ensure whatever you buy has a full service history and the correct specification of oil has been used. This is an absolute must. DPF problems are probably inevitable if the incorrect oil has been used. If in doubt, avoid.
