The article reads like a press release from BMW, but it has quite a bit of detail. Particularly this:
The optional Tyre Pressure Control system reliably informs the rider of current tyre pressure and makes a significant contribution to both riding comfort and safety. Tyre pressure data is provided by battery-powered sensors in the wheels, with either a yellow ‘information’ lamp or a red ‘warning’ lamp in the Info-Flatscreen informing the rider as soon as the pressure measured deviates beyond the margins allowed from the pressure required. TPC is scheduled for introduction in autumn 2006 and may be retrofitted as special equipment for all models following the start of production.
Sounds like a negotiation point. Obviously you're going to pay MSRP for a first-off-the-boat GT. Seems reasonable to ask the dealer to agree to throw in the not-yet-ready bells and whistles at no additional charge.
