In regard to the DAB+, I've changed my view on it since I sorted out my equaliser settings.
It's quite good and when I run split-screen it's good being able to see track and artist information, it lets me check out more music by an artist I like when I don't catch the back-announcement.
The tint I had the dealership do prior to delivery is top notch, and I know I get to take it straight back if there's any problems. Again, having had time in a car with no tint (and I do a south to north commute so I get blasted with the sun morning and evening) I wouldn't have it any other way.
I have the Extended display and have spent time in a car that doesn't have it. It's not a must have, but I'd definitely choose it if I had a "go-over".
