Mondeos' were on the K mate..............that much is true.

My honest opinion is he was a chancer. Thats aid, just keep an eye out for the next week or so. Keep the doors locked, keep the curtains closed during the day when you're out. Idf he wanted your car he'd not make himself known to you, he'd watch until it was there and then have a go at the car. Make sure the keys to the cars are hidden away from sight when you're in, and not on the side by the door.

Don't think you've anything to worry about mate.
