As a further consideration, may I suggest that you start phoning dealers not too far from your current local dealer and than phone dealers a bit further away until you find one that can offer you a stock ID.3, either the trim you are looking for or close enough.
This exercise may seem a given but it worked for me as I discovered that there are a good number available, to a point that you can begin to chose what is being offered from several of them.
Should you be successful, you can then source the car from further a field where you have found one and revert back to your local dealer for any fault issues and servicing under the Motab scheme.
As for me, I complained to the Divisional Head of Sales about the preferential selection of allocating to customers and he apologised and instantly offered a Valet and Lifeshine Protection for my ID3 – worth about £299.00 – I’m still considering how to respond. But earnestly, I wish to act so that other Motab customers can also benefit or at least not face this type of selective patronage.
