IMHO, £22k is a 'we don't really want to buy it' offer; however, as has been said, there is also an element of the need for any dealer to build in a buffer to cover themselves in terms of the Consumer Rights Act of 2015. Also, any dealer will be factoring in sitting on the car for 6-12 months; whilst it is unlikely that a 2016 Morgan will depreciate vastly in that period of time, the dealers money is tied up (or they are paying interest), hence another cost.
The sad fact is there are a lot of Morgans that are still up for sale and have been since this time last year or longer. What we have seen on here is getting the price right is key - Perry put his 4/4 Anniversary up and it sold quickly; however, it was priced keenly.
Steve109, your last comment makes the most sense to me - a keenly priced private sale will net you more than a dealer trade offer.
In terms of Steven (1560's) comments, although I agree that winter isn't the ideal time to sell a cabrio / sports car of any kind, I do think our continental European members have benefited from a more buoyant used Morgan market. Perhaps less supply of LHD cars means more demand but prices seem better in the EU and the market, at least up until now, not suffering the same level of used value slump we are on these cars.
