The problem with Morgan is pricing of the extras (the base car would have been low to mid 90's) and that they are considered "bespoke", each car being specified to the tastes of the first owner.
£25k of extras on the new Mog won't equate to anything like that when the first owner wants to sell.
There's an article in the latest MOG magazine aligning bespoke Savile Row tailoring with bespoke Morgan cars. Great, both are handmade and take longer to complete than a machine-made item. Problem is. as and when you come to sell them, the suit may be OK, but it's not been made for you so doesn't quite fit perfectly. The same for the Morgan, you have to live with someone else's decisions.
Pre-CX that might not have caused an issue, demand exceeded supply. Now, perhaps, supply exceeds demand and the pre-loved market is feeling the impact.
