My 2012 X5 diesel is in the process of being built still. I asked my CA if she could add the hitch, but she told me it's all done at the dealership. In doing my search, I saw that some people had it done pre-delivery.

How is that possible? My CA said they don't do it at the factory. My plan is to mostly tow my mountain bikes, and I already have a bike rack.

Any advice? Btw, dealer wants $1200.
