[Mulberry]

I forgot to mention that two other options that I would consider a priority would be the front and rear parking sensors and reversing camera. I've got both on my X1 and they make parking in tight spaces etc. almost a joy.

Regarding which wheel style to choose, don't forget that the M Sport will have sports suspension (lower/stiffer) and sports seats that the Xline doesn't, and this will make the 'feel' (ride/handling/comfort) of the models fitted with the same 19" alloys and runflats different.
