Thank you guys
About radio reception:
I have the HK and DAB option. I normally listen to DAB, and when a station is out of reach (as DAB-stations send mainly in and around larger cities), it automatically switches to FM. Or vice versa.
I have so far not paid much attention to the FM-mode, but will do the next days to give a better answer.
About 17" inch wheels:
The M-suspension and 17" inch rims are definitely a comfortable combination. How sporty it is I don't know yet, since I just got the car
I chose 17s since I use the car mostly in city traffic with poor quailty on the road surface.
A friend at Michelin told me they had tested different sizes, and recommended 17" as a perfect compromise. If my driving scheme were overland journeys or distant commuting I would probably go for the 18"s. Maybe mostly due to looks.
So far I have done too little of inspired driving to have a qualified opinion myself, but from what I have experienced these wheels are capable of pushing hard through the turns.
So far the car surprises with a quality feel from at least one class up. After more driving I'll give a better report. But it sure looks promising
