OK. Now I can finally reveal my soul, and not to be killed for that.
The car is officially named (as I already subtly hinted above):
Rolls-Royce Phantom Drophead Coupe 
A hardtop version will be named RR Phantom Coupe. Coming in approx. 1.5 year.
Corniche & Camargue will be used for a baby RR convertible & coupe. Along with Silver Shadow (Spur, Cloud, Ghost, Wright) - which will be a sedan.
