Couple other thoughts-
Trim: standard trim needs upgrading, satin silver looks cheap. Personally I think wood looks best with beige and would go for fineline. This is £345 upgrade on SE but again only £100 on M Sport (closes the gap even more!)
Power tailgate: I have this on the Q5 and always will again. No more dirty hands.
Current 2016 F80 M3 Saloon, Alpine White & Silverstone Full Leather. Love it.
Past 2015 F13 M6 Coupe, San Marino Blue & Opal White Individual Leather. Gone but not forgotten.
