While their $10K asking price for a bike with this level of components is not outrageous, especially given the exclusivity of it, you could build this exact bike yourself for under $6,500 and then just slap the Lexus and F-Sport logos on it. I am in the process of building a similar bike right now and thought it would be cool to do a black & blue color scheme like my ISF and put the F logo on it, and in doing some searching for logos that's when I came across this thread.
Here is the complete parts list along with the corresponding costs:
Frame & Front Fork - 3K Carbon Fiber: $400
Handlebars - 3T Ergonova UD Carbon Fiber: $105
Stem - 3T ARX UD Carbon Fiber: $65
Headset - FSA Carbon Fiber cap: $60
Saddle - Selle Italia SLR Carbonio: $195
Seatpost - FSA Carbon w/Di2 Battery mount: $170
Groupset - Shimano Dura-Ace Di2 (Levers, F & R Derailleurs, Brakes, Chain, Cassette, Crank, Bottom Bracket): $3,710
Pedals - Shimano PD-A530: $66
Wheels - Shimano Dura-Ace WH-9000-C50-CL: $1,500
Tires - Panaracer Race Type A: $90
Total cost: $6,361. And you could save some serious money by going with the regular (non-electric) Dura-Ace 9700 groupset which is only $1,619 - bringing the total cost down to $4,270. Still one hell of a bike but just with manual shifting instead of electric. You could also go with the generic C50 wheels for $410
instead of $1,500, lowering the total price to a much more reasonable $3,180.
