and the prize for anticipating a cock-up on Mr BMW's behalf goes to.... trapdoor!

Just rung the dealer to order the new ULF... "oh, can you just confirm the price on that please?" "one moment" (sounds of keyboard tapping) "£412.62" "you what? you said £268.21 on Friday"...

Abbreviation of what became a long conversation, he will sell it to me at that price, which in turn is cost price!

So, all-in-all, have got a fantastic deal - but not one that is likely to be repeated! Should have ordered half-a-dozen at that price in retrospect!
