Had a couple this weekend. On Saturday, I passed a rather nice silver 458 heading along Henhurst Road near Gravesend. I'd just given him a thumbs up and then noticed he had his phone to his ear. Respect lost - don't believe a car like that doesn't have Bluetooth.
Sunday, I was driving up to Norfolk to visit my parents. Think I was just outside Needham Market when I passed a DMC Delorean. Got home later and triumphantly told my girlfriend what a cool sighting I'd made. She'd been down in Sussex for the day, her response? "Oh, I saw a McLaren P1 today". Always has to go one better :/
