I think that part of the slow down could be that 'mid life crisis man' wants a car from his youth, so fast fords, ferrari's etc from the 90's are more in demand. Car's from the 30's appeal to a totally different demographic.
Many Morgans aren't priced to reflect their current value/worth. Last year's prices seem to be being held on to, perhaps if a dealer owns the stock they can't take the hit, but if it's a private or commision sale, only the 'motivated seller' will move their car on.
Don't worry about depreciation, it's just part of the cost of ownership.
