I had something similar with my car order from a local dealer, not via Vanarama:
I ordered on the 2nd November 21, MG said that the order date was the 18th March 22 (about 20 weeks later). After much discussion trying to get to the bottom of this, I finally found out the reason:
My dealer received the order from me and placed the order onto MG on the 2nd November 21. However, as was their usual method of ordering, they did not put a customer name (my name) against the order - it was just for a LR T in red. You may remember that MG said that they were going to cancel any orders without customer names so my dealer finally added my name to the order on the 18th March 22. My dealer and MG said that this change would not affect the likely date to receive the car and I am currently being told that the car is at sea, arriving in a couple of weeks time.
So, you may not have lost the 2 months in the build queue, as the queue may still be from the 22nd November 21.
