UPDATE:
So thanks for those that have responded, I do appreciate your help in my search.
From responses and other investigations I believe I have narrowed down the search criteria.
Colour. White or silver. Unfortunately I have a grey M135i already and two greys don’t make a right ! Blue does seem to age and black, although lovely is a devil to keep looking pristine. I had a black Range Rover that showed every mark.
Age. Post march 2012 for the roof opening on move function. In the U.K. you can have sun, rain, sleet and snow in a 30 minute drive.
Engine. Goodness, a difficult one. I love my m135i, the acceleration of the bi turbo ( I’m not really worried about the gender orientation, just that it goes like @@@@ off a shovel, which it does. However I can’t really justify two fuel hungry beasts. And, considering the minimal use of the z in mainly fine weather, I suspect I will survive with a mapped 2.8 a think of the car tax saving! Although I am prone to change my mind on this when the speed monkey on my shoulder speaks!
Professional nav is a must. Yes, I know it’s rubbish and Tom Toms are better, easier to update etc etc. But, I want ease and nothing to disconnect every time I pull over.
I love the adaptive suspension in my M135i but may be able to live without it in a 2.8i. But sports suspension is pretty high up on the wish list.
That’s all folks. I really appreciate any responses.
Have a good day forum.
Joe
