Looks like the 330e is now available to build on the UK configurator.

I have been told (by Douglas Park BMW Glasgow) that UK cars won't be available to order until around September.
I've ordered my 330i, hoping it's a better drive despite the extra £180 ish of company car tax a month.
It also doesn't show the M Sport Diff when you config the M Sport Plus package... I assume it doesn't have it then??
