Yup, last week. I was pushing the Robin Hood (on wheel skids) over to the side of the garage (so I had enough room to strip the Sapphire) and managed to hit it against the wall, snapping it off the stem :-( - Tw*t.
Couple of times - the most recent when I took a corner wide (but within the line) and the third party took it tight. Didn't cost me owt as it was a company vehicle.
Not broke any of mine but someone did hit mine when I had an Impreza and it did nothing to my mirror but smashed his. That was justice for pushing his way through.
