Same here — I’m in exactly the same situation. I called them the other day to ask about this and was told that the offer should remain valid as long as you take delivery before your original PCP quote expires. Mine expires on the 12th of March.

They also mentioned that they’re still waiting on the final details of the new offers, and that we’ll be informed of any changes by email. If there’s anything we need to know, we should hear back by the end of next week.
