What a major fail. The dealership should have done the right thing and let you run about in the white one until the new one with correct colour turned up. This happened at my local dealer when an extra wasn't included!!
Anyway glad you got a better deal.
I would have had no qualms if they had offered me the white car as a loan car but this wasn't the case. In fact it was the opposite they said the most they could offer any sort of loan car to a customer was 1-2 weeks.
I was also pee'd off that they tried scaremonger tactics in telling me that I couldn't have a blue one until December if I re-ordered. Basically they were trying to force me into taking the white one which I saw through.
When I cancelled the order and got my deposit back all of a sudden they could do October if I ordered today as they had pulled some strings with bmw factory.
No thanks changed dealers and got a 2k better deal including more options.
