If nothing is rubbing, falling off or likely to snag then I cannot see it getting a lot worse. You could always give a local quickfit place £20 to slide it up on a ramp and have a quick inspection for risk mitigation then go to the dealer. They might even be able to tell you if they think it is in the box etc to help. Despite the mud often slung there is a usually a more trained one among them who is happy to lend a hand.

Everyone loves a Morgan. Even me, unless it's broken again.
