Having thought long and hard about this I think it's ridiculous that now having a FBMWSH seems to affect the value of a car!
My Inspection II is also due in around 3750 miles, seeing as I've forked out for the top warranty then I'll probably use Andy at Murkett's this year and make sure every tiny little thing is sorted out to perfection, after this I won't be buying the top warranty, maybe just a drivetrain warranty with a £250XS and keep the BMW EU Breakdown which is handy.
I've already have a chat with Simpsons about servicing and can safely say I'd save a lot of money going there and no doubt the service would be perfect as well...
If i'm not going to sell the car which I 'probably' won't

then I personally don't care about whether or not it's got the FBMWSH
