Prices are falling on most cars.
A Morgan sitting in your garage is a chunk of money. You have two choices.
Sell it and get hit on value.
Use the car rather than have it sitting there. Get a return on your " investment" in the form of enjoyment.
Looking at the low mileages on so many Morgans makes me question why they were bought. That adds to the resale conundrum of low mileage so pay more as that " low mileage" carrot becomes a false idea. Expectations of value need readjusting in today's world.
