[gippy]

hi folks,
i'm finding my 2016 440i to be, to be frank, a bit boring - and here in the UK i could get a 2013 i35s with a few grand in change....

got some questions though:

- the iDrive unit is an older version - can this be swapped out for one of those touchscreen Android jobs, like i can in the F-generation cars? (a pro Nav style unit)

- how does the N54 twin turbo compare to my B58 for tunability/reliability?
i know the B58 is still relatively new but its easily mappable to around 400bhp - can the N54 be mapped to a mid-level tune without much effort?

- does the car come with LSD or can this be added later?

i'm going to test drive one at the weekend - i'm hoping for better sorted suspension, better body control and something that's altogether a bit more 'sporty' than my current car!

thanks!
