Glos Guy, I’m going to guess that as they seem to have changed the rules, they will apply to new leases only.
Yes, I speculated the same earlier in the thread. It would make sense and explain the revised wording on the website and the fact that those with existing leases are being given prices. Anyone ordering a car now in the expectation that they will buy the car at the end of the lease would be wise to assume that this will no longer be possible for new leases.
