i have own a large volume of cars, like you i have my creative mind, but i always think what i call " SAFE SPECS" , so when i decide to get rid of one i sold it fast and at a correct price.
Discussing recently with a well know Morgan dealer that the majority of the car easy to sell are in traditional combo colors.
I know Morgan is not supposed to be resell but we never know what can life bring to us
This is simply my own opinion and i am sure have many different opinion here and there
