Everyone has their own favourite colour and you have to decide yourself -- although I don't think I've seen a Morgan with a bad colour -- even the mad orange looks good. I went for Etna Blue, which is the colour used in their 2025 CX marketing campaign. It's an old Porsche colour from the 1960s and I thought it matched the old-but-contemporary look of a Morgan. For others, (British Racing) Green is the only choice because it is old-and-traditional.
I would be concerned that the very light (biscuit) seats might get dirty, as you will presumably be driving with the roof off 99% of the time and a lot of muck gets blown in. On the other hand, a lighter interior does brighten up the car.
I chose Auto. Again, this is a personal choice - many Morgan owners would be horrified at the notion of Auto. In my view the BMW gearbox does a far better job than i can -- gear changes are 95% accurate and very fast - and without gear changing, there is more time for me to just enjoy the ride.
Did you spec air conditioning and the Sennheiser system - again some Morgan owners wouldn't have either, but we have used the air conditioning a lot in the last few days (30 degrees!) and both these options are good on those occasions when you get stuck in a traffic jam. However the sound is pretty inaudible once you drive hard.
Also the Nitron suspension - this is excellent and some people would put this top of their list..
