I was in the market two years ago for a bike in the sort of $6000ish range. I knew what I wanted and contacted the local dealer, of which there was one. The configuration I wanted was going to be a purely custom order (frame of choice plus disc brakes plus Ultegra Di2 in a 56). This bike shop is probably the most respected one in my town over the years. They were absolutely responsive and great as I sorted what I wanted. That said, I had to buy the bike in order for them to order it from the factory. The owner told me they just cannot be ordering $6000 bikes to sit on the floor any time someone expresses an interest. The dollars just don't work out. I totally understood.
I ultimately decided to ramp back my purchase and bought a nice BMC with 105, planning for an electronic shifting bike down the road (where I am again now). I am sure the same situation will apply now as I embark on another bike purchase.
