Got email response from MG UK today as follows FYI -
Thank you for your correspondence and I’m sorry to hear your disappointment about the late delivery.
We would like to let you know that the New MG ZS EV Long Range has been an incredible success since its launch, there has been a high demand on this vehicle.
We understand your frustration, unfortunately, as my colleague has suggested, we cannot confirm the exact arrival date until production of your vehicle starts.
Current lead time is 8-9 months from the order date, however, please be advised that the ETA is subject to change, depending on a number of factors, including but not limited to shortage of semi-conductors, logistic challenge, etc.
MG fulfils customer orders including the retail and motability customer orders as per the oldest order date, however, the production date varies by car spec, hence it is not always comparable with other orders.
For the dealer stock on Autotrader, I’m afraid that we cannot comment on this without further looking into it in detail. However, if the dealer has the stock arriving, it could only be the case that the dealer stock was ordered before your vehicle order.
As your order was placed in January, we believe it is not long for your order to be fulfilled. We would recommend you to follow this up again with your purchasing dealer in 2 months and hopefully you would be able to hear some updates in due course.
