Marko I share your sense of wonder - A few of us Irish enthusiasts regularly scratch our heads at the regularity at which "new" 131 Sports are discovered - Despite all the stories of rotten, scrapped and crashed cars a surprising number seem to have survived against the odds.

You could start to advertise "new" 131 Sports if you were to restore them to the same standard as your current project car!
