Re: What's the scariest car failure you've had while driving?
Not really frightening this one - parked on the side of the road eating a snack with girlfriend (calm down!!) there was a soft 'clank' from the rear of the car. Investigation showed that the rear exhaust hanger had snapped... luckily I had a boot of tools and spares (it was a Citroen GSA after all!) so I was able to sort in out in minutes.
That's the only one that could be termed Car Failure
rather then Driver Error
