I went for Vega Blue, I like it better than Paris or Burton (the other 2 blues available in the UK). brighter and deeper shine. McL of course charged me a fortune as MSO bespoke...as if they didn't have a truckload of Vega Blue paint ready to do the 570 for which it is a normal color...Beautiful! What color blue?
Dealer says mine is the only 720 in Vega Blue, but there are others probably by now. Car is April 2018.
