Differences are basically cosmetic. Different front spoiler, extended side sills and different rear bumper configuration. M Sport brake calipers, M Sport badge. Fully digital dash and 10″ Infotainment display as oppose to 8″ in the Sport. I’d have loved the M Sport, but the I’ve specced 19″ bi colour alloys and phytonic blue (which isnt available in M Sport) so it’ll stand out in the crowd. I’ve also gone for the Tourer, which are quite rare in the UK.
I’ve got the 19″ alloys too and they were well worth the money. TBH I prefer the Sport looks compared with the M Sport. The dash certainly is clearer and easier to read than the fully digital M Sport one. You must post some pics when you get it.
