Good question!
I'm planning on changing at some point this year. So far, my short list looks like this:
BMW 530d M Sport (current shape)
BMW 335d Tourer (e90)
Audi A5 sportback
Audi S4 (3.0 TFSi model)
Jaguar XF
Mk6 GTi
Or a New Golf GTD on a lease.
I was going to change at the back end of last year, but my head hurt from thinking about it. I've held out, as there's a possibility of a career change ahead. For the time being, the GTi will do :)
