Modenising a Morgan could be a away to attract new buyers.
Morgans ate pricey for "old school" mechanical design and the age of Morgan owners is fairly high. There could be scope for cars with modern suspension and some of the other suggestions mentioned here. An option for modern or trad versions could work.
Eventually electric will come in......
Many younger people love the look of a Morgan borne out by comments made.
I think it is price and the thoughts of antiquated mechanics deter them.
