I have the Sport Nav (2018)
The 2ltr naturally aspirated engine is powerful enough for most, certainly economical if driven sensibly. My 15 mile commute returns 60mpg but it is mostly motorway, i tend to drive between 60 and 65 , but equally accelerates briskly enough if you want it to.
Cabin is noisy, too noisy IMO but maybe because the Sport Nav has lower profile 18 inch wheels...maybe.
Bose radio, lots of people make a thing of it but i'm not that impressed. Because the cabin in mine is fairly noisy, it kinda overpowers the radio a bit, but again, that may be tyre choice and 18 inch low profiles.
HUD is brilliant, instantly displays any changes in speed limits and you current speed, also some basic Satnav info if you're using it.
Satnav is fairy good, open the centre console bin between the seats, the Nav SD car goes in there. If it's not there, ask why or you may end up having to get a replacement.
6 speed gearbox is lovely, comfort is good.
Its possibly the best car i've owned, love the looks, love the interior but it has it's shortcomings. Nothing major, just niggles really. I'd have another without doubt.
