lol This is not done via BMW direct (there's fat chance of them matching this deal) so you've got little chance of pulling that off as nice as it sounds Dem.
There are always going to be cracking lease deals through the right channels so don't worry mate as I am in the same boat (6 months into a 2 year lease) and can't wait for the next one, to try something different. A year would be better in a way.
