No, you do not have to enjoy mechanics to run a Morgan. It does help. With the newer Morgans, all that needs to be done is a regular greasing of the front suspension (2 nipples each side) every 250-500miles, or say once a month. You could choose to ignore doing this, but expect the king pins to need to be renewed at about 12000 to 15000 miles. Just factor that into your running costs.
I grease anywhere between 1500 and 2000 miles. It does'nt seem to have reduced the life of my kingpins as I'm still on the originals after 66000 miles.
