I've had a better look and cleaned up the mess. Not as bad as it looked at first-- vertical split in bumper cover, fog light / mounting surround destroyed and small grill gone but mounting points still there. Nothing wrong with brakes, just me paranoid and expecting the worst after all the recent troubles with the car. (Infamy, infamy, they've all got it in for me!)
Can't get a bumper cover quickly but the body repair shop man says he can repair it ("not worth spending too much on an old car" -- I like his pragmatism.) I already have the fog light bits having bought them secondhand some while ago (how did I know?).
Thanks for the offer MutantCav, the car is titanium. If the bumper repair looks good I can live with it. I might pursue your offer after we return from holiday, if the repair doesn't please me.
Anyway, it looks like I can get car the in a fit state by Thursday.
This is why I prefer "don't care cars", less need to worry about them. Even so, it's a shame to turn the miggy from a "nice car" into a wreck quite so soon.
Thanks for your help.
