believe that BoS will make a liveried version:
1) Remove the Alfa logo on the cowling
2) Add the 4 sets of numbers
3) Add the Scuderia Ferrari logo on the bonnet
4) Paint the exhaust system silver
5) Paint the rear suspension bits with dark silver to look more metallic
6) Paint some of the front axle black (see photo below)
Finally, the really tough part: determining what color to paint the wheels and the grill. Should the wheels be dark silver/gray or black or red? Should the grill be black or red? Based on the few pictures, I'd go with dark silver/gray wheels and black grill.
