I understand what you mean.
And i agree, the good condition bonus should either be paid on order of the new car (not on delivery) – or the GCB should take the prolonged wait times (sometimes a year) into account.
I do know that they pay GCB pro rata if you extend your lease. I’d assume that, if you actually have to wait a year, they’d throw in some extra. If not, then they should.
