Had my 156 for just under a month now and i love it, however today i parked up at a friends house, just about to walk in and heard "clunk" for the car, turned around to see it rolling back off the driveway, had to sprint, open the door (good job i didn't lock it), reach in and pull the handbreak on hard to stop it from smashing into the car parked across the road, only inches to spear. Now how embarrassing would that have been?!!!! The thing is, this is the second time this has happened. The last time i had a call from a neighbour who found the my car in the middle of the road. Now is it me been a little limp wristed and not engaging the handbreak properly.........or is this a thing that is common on Alfa's?
