Thanks, Richard!
Ken, you're right about that, making the factory tour is a must, except my wife would perhaps stab me if I would suggest taking a trip from Portugal to the UK just to see a car factory.
Getting the car is the only excuse I had to do it, and it looked like it was slipping through my fingers, you see?
Lisbon's dealer has meanwhile told me that I'll still be able to collect the M3W in Marlvern, and won't be affected by the changes in legislation, since this was an arrangement I made with the dealer prior to these changes and they'll honour their word, as would be expected of Morgan.
Uff, that's a relief.
