I suppose it depends on how much you think your inconvenience was worth.
I had to cancel a week's driving holiday when BMW couldn't get my M5 back to me (with more than a week's notice) when their 'master technician' working on it went off sick. Their other master technician didn't have time in his schedule to fit mine in (despite it only being for a 30 minute timing chain tensioner replacement).
Lost out on hotels, ferry and holiday and had to hire a car for the week to get to work - and after all that they tried to present me with a £1500 bill for a damaged sump as they said that was contributing to the leak (it wasn't as there was no leak until the tensioner diaphragm blew).
After weeks of stalking their dealer principal (BMW GB were not interested) I got a face-to-face with the service manager who asked me what I'd be happy with, so I presented him with a list of the costs/losses I'd incurred. I pointed out that the £1k bill would be going to the small claims court if this meeting wasn't productive.
Got the £1k taken off the bill (which was better for them than a £1k cash settlement or a CCJ), so was ultimately happy at the outcome, but still peeved that it took so much effort on my part to rectify their errors.
If they'd refused the compensation and told me to book a meal on them, then I'd have been doing the full tasting menu at Le Manoir Aux Quat Saisons
