Is this not the one that has been up for sale on the Maserati Club website (and elsewhere) for about £53k for last 6 months or so? That was also a 1 owner, UK car with less than 10k miles.
If it's the same car (as I strongly suspect), either Supercar Rooms has it on SOR, or they've bought it and added a tidy 5 figure margin.
Anyway, good luck to them.
