We're all different but I wouldn't compromise my choice on the basis of reselling.
I chose carefully and I'm in it for the long haul anyway, but too many Morgans are specced in a conservative way, and so there will always be a choice on the market of those traditional colours, and interiors.
Most buyers set off with an ideal combination and then compromise to get the closest to that spec.
My choice would be stainless wires, spare wheel, manual gearbox, walnut dash. Dark interior...black, or at a push red or green. I wouldn't refuse orange.
Exterior must be bright.........no metallics, and nothing in the black/grey/silver spectrum.
That's how I ended up with a red Roadster. It was the closest by far to my ideal.
