Help me decide

Hi everyone, 

I'm in a bit of a dilemma I really don't know what 5 series to get. 

I have about 20k to spend It has to be 2012 + and a touring my absolute ideal would be a f11 m5 but unfortunately they don't exist! I had a f11 530d but find it lacking, it's a great car I loved it but just found it a little flat and runs out of puff quickly. I currently have a saab 93 areo 2.8 turbo petrol. I do about 10,000 a year 20mile road trip to work. So my question is what are peoples views on say the f11 535i ? Or 535D? And phaps when there tuned a little aswell? Or maybe other options that you think may suit ? Dare I say in audi s6 ?

Thank you everyone in advance.

My brother inlaw runs a 530d touring he commutes into Europe so racks up the miles, his car is remapped to just over 300hp and 600+nm it is ultra reliable and still returns 40+ mpg in daily use. When he wants it though it is demon quick, for his use its perfect great at Autobahn high speed cruising plenty of space comfortable and quiet but happy in town.

Me I always go for the big engine then look at tuning to make it a bit different. It never seemed right to me that my business partner and I had the same car when he didn't have a clue what he was driving and worse didn't care so mine were always a bit special, still are.
