very nice spec, congrats! now the waiting begins....not sure on lead times on the GC, I was quoted 6-8 weeks on my vert last year. Car arrived 16 weeks later, it seemed like the longest 16 weeks ever but definitely worth the wait.
BTW I have cinnamon brown and it looks great, I also had this on my 535d and I experienced no issues with selling the car or the residual value offered by BMW
