I know that the risk of a doom spiral is quite high, but...........

Not only are there a lot of CX cars for sale, there also seems to be a hell of a lot of trads for sale as well, many have been sat with dealers for months and months.
I think that dealers do try to build up a bit of stock in anticipation of the spring/summer 'rush', but some have 25+ cars in stock, with probably 4 to 6 CX cars in that number.
I would guess that a lot of cars are on SOR, it would surely be beyond the financial resources of most Morgan dealers to 'own' them all.
The cost of the CX cars soon pushes the value of cars in stock well over 7 figures, and nothing seems to be moving...!

In the 'old days', when the most expensive car in the range was £70k ish it made up a small percentage of the total sales with the bulk of sales being more 'affordable' 4/4's and +4's.
Spec of cars remained unchanged for decades, people knew they were buying an already old fashioned and outdated car, but they were happy with that, and they were also happy to wait, sometimes for years for it. They knew it would leak, creak and rattle, but they were happy with that.

Now, with the starting price being well over £70k it would seem inevitable that sales will dramatically fall off. Where or who is the market? The US?

MY updates like 'real' car manufacturers, changes of spec, new tech and 'modern' features all cause quality issues for the hand building work force in Malvern.
When prices are pushing towards, and in some cases past, £100k there can be no excuses.
I was fortunate enough to go to the Porsche experience center at Silverstone again yesterday. When you see the what £70 to £100k will buy you from Stuttgart you've got to question the direction that MMC are going.
