I don't know how reliable these sales numbers are
https://www.goodcarbadcar.net/morgan-europe-sales-figures/ and in future 335 units are heading to the USA it doesn't leave a lot of spare capacity/ sales for the rest of the world, especially the UK, to support an extensive UK dealer network after Morgan Works has taken it share of the sales market. I know there are plans to build upto 1000 units a year, but I doubt, that's going to happen overnight. When I was there in December, 17 units was the weekly target (annualised about 850 units) and you couldn't move easily about the place for cars/chassis and most of the cars where LHD heading to the US..
When it comes to the UK dealerships, it would be interesting to understand how much of the dealerships profits are derived from new car sales and how important that is to their business model in order to survive. With the growing cost of demonstrators and the shortening of lead times from order, it must be harder for the dealerships to fund their demonstrator fleet, knowing that cars can be delivered to customer specific orders quite quickly, reducing the desirability (unless major price reductions) of their demonstrators to potential customers. Generally long lead times help demonstrators to hold their value and increase saleability.
Always interesting to try and understand why there are fundamental changes at dealerships, they are not always due to market conditions, other issues like upcoming ownership retirement etc. can influence changes
