The F01 is a big car. The F10 is near dead on with the 7 swb. I just detailing my Imperial blue 535xi and couldn't do it for that price based on materials alone. Imperial Blue is as bad as black. Show's swirls no matter how hard and careful you work at not swirling it--of course washing by hand.
I ended up claying, 1Z PP, Menzerna P085RD, plus two topcoats of Menzernal Powerlock. Cleaned up from both the factory and the detail. If I were to do this car for someone, I would charge at least 500 bucks.
F10 turned out fantastic. all swirls were removed. i broke up the time, but spent about 16 hours on the clay, polish, wax for the exterior.
The crap the dealers use, a glaze with a filler is gone after the first couple washes. best is to remove the swirls entirely--whichi isn't easy.
If i jumped into a 7 (maybe incentives due to the redesign will come out soon) it will be silver or space gray.
