Broke the V70. 
The button on the gear knob broke and fell out, and I can only use D and N. 
It happened just as I was about to set off for Dorset from South Wales and I was in a cul de sac facing the wrong way!
I managed to turn around by going up on the pavements, which was lucky as the V70 has a crap turning circle. Once I was pointed in the right direction, I didn't stop until I got home! 
Being a bit of a lad, one of the crappier vans they gave me back in the day - a really shagged 2l petrol transit - I always used to think it was really funny every lunchtime to race into the (tiny, tight) carpark where a few of us used to meet for lunch, slam it in reverse whilst still going forward at a rate of knots, and effectively do a handbrake turn so it was facing the right way to leave. If the handbrake worked, I would have used that instead.
Needless to say, after a few weeks of this, reverse gear just became another neutral.
Rather than yet another driver misuse form, and as I knew it was due for replacement, I just drove around everywhere not using reverse for about the next month
