As the bleary-eyed emerge in clouds of the vape smoke from Sin City’s - ahem - related service industries, my morning has just got considerably more Reservoir Dogs. I’m waiting in the plush surroundings of the Aria Hotel’s casino for a man called Mr Fish. I have no idea who Mr Fish is, what Mr Fish looks like or what Mr Fish does. But I want something that belongs to him. His car: a unique turbocharged, matte black super widebody and slammed Porsche 964.
