Off topic chat about anything you like. Doesn't have to be about XMs (though they will inevitibly come up!). You can even discuss non-Citroens in here!
I've bought one for my estate, especially as it says it doesn't involve any drilling so no holes in the bumpers. I've never really had any problems with parking, I just wait until I feel the towbar crunch into the other car! but at £39 quid I reckon it's worth it.
I was so impressed with the one on the BMW I breifly owned that I fitted a cheap after market set on my 406 - brilliant it screams at you for a blade of grass but cheerfully lets you back into a wall or another car.
