If it’s a brand new Morgan from the factory, I have never yet heard of any discounts on price. May be a different story if a new one has been sitting in a showroom for a year or so.
Yeah, it's difficult to imagine why MMC would be interested in discounting the price of a new bespoke car, it's not like they are having problems selling them. The second-hand market, on the other hand, is a different proposition, there are plenty of used cars out there and I'm sure there would be room for manoeuvre with some dealers, depending on the car.
