Got the 'Vette Grand Sport convertible and the Amphicar at the local Tesco today (naturally there was a conspicuous lack of Datsun 620s, Transit Connects and Espirits), while I got the Charger at a shopping mall elsewhere. I guess said mall isn't that popular with the Retro Entertainment scalpers.
I'm thinking of setting the Amphicar loose as its card and blister is pretty beaten up, plus its front axle looks like it may need straightening.
