There are plenty of folk on this forum raging on 'Where is MY car as Chorley have been allocated 60 cars?'
There is a very simple answer.
SAIC (MG) build in batches NOT to an order.
VW, Ford, Mercedes all build to an order. The dealer puts the order in and your car is given a slot to be built, and some you can follow it along the production line.
Not so at SAIC!
Re the MG ZS EV range, there are 6 options (forgetting colour) available in the UK.
SE SR, Trophy SR, Trophy Connect SR, SE LR, Trophy LR and Trophy Connect LR.
I have no idea what size a batch is, could be 500, 1000, maybe 2,000 or even 5,000, who knows.
Also we have no idea what the true state of the order book for the UK orders is, as that is commercially sensitive.
Maybe there are 400 orders for the SE SR model, and 500 turn up in the batch destined for the UK.
Therefore MG have 100 SE SR cars going spare, Chorley take 60 of the spare cars.
No person has been usurped and got a car before anybody else, because only 400 SE SR cars were ordered!
Untwist those knickers now!
MG (SAIC) will always try to satisfy the 'exact' order i.e. the colour.
They can't offer you a SE SR when you ordered a SE LR, you would lose your government grant in the first instance. The only thing you can change without penalty is the colour.
What does need to happen is representation from MG UK to SAIC China to build a batch or two of the most popular model be it Trophy LR or Trophy Connect LR.
That of course is dependant on the various chips and wiring looms being available!
Those batches have to integrated into the ROW LHD cars, now we can see why things don't just turn up on our shores!
Mg i.e. SAIC are beginning to understand how European car manufacturing works, a be it slowly!
Tesla have the same problems but seem to manage it better!!
