Agree that the wait is long however, what I think would make it more bearable would be if they introduced a order tracking system similar to that of the USA.
I think 6 months is in line with the competition - q5's also have a 6 month wait as do some vw's. In my view dealers in the uk need to start reserving build slots with standard orders then allow customers to customise when they confirm a order with deposit. Maybe this happens already but who knows.
On a side note if there is appetite I ll post some pics of my x3 when I get it next week, spec is:
19" 309 alloys
Black leather with brushed aluminium
Rear view camera
X line package
All weather mats
