Agree, IMHO star silver is the best colour for any TS variant but of course it's down to individual choice when it comes to colour
Also I didn't think the Arden blue commanded any extra coin both new or S/H ?? those 3 colours available are all metallic and the Arden blue is also the more common or numerous so plenty around in that colour, the black is the rarest or lowest number sold of the TS turbos...
Maybe someone selling an Arden blue might try asking for more, but it's definitely a buyers and not sellers market out there when it comes to selling a used car...
