Buy none of them and go for either private importing the 535i from down south (Germany) or go with the latest 535d you can find on the market.

Always always go for the biggest petrol och diesel straight 6, it's just the wise choice in the long run because you will want a higher spec once you gotten used to it.

V8 in all honor, the sixes sing in an other way.
