Car pinched one of just three in SA

A thief who broke into an Adelaide home and stole a new car may struggle to fly under the radar, with only three of the models registered in the state.

A man entered a family's home at O'Sullivan Beach overnight, pinched the keys to a 2016 Citroen C4 Cactus wagon and drove off, police say.

Police are asking anyone who may have spotted the distinctive red and black vehicle to contact them.
