Yes, I was going to check out Bell And Covills too, they aren't too far from me either and I definitely want to look at a good few cars before making a decision.
You joke about being withing walking distance of a Morgan Dealership, but as it happens Richard Thorne really are very close - I literally could walk it if fancied a good bit of fresh air! They aren't an accredited dealership any more, but as i understand it that's just because they dropped the franchise to save paying a subscription to the factory.

With my intended use of the car dealing with some reliability issues wont bother me too much. I'm not expecting it to have Toyota levels of reliability, or even Aston Martin levels of reliability, but I figure in 40 years I'm less likely to regret buying a M3W which gives me trouble than I am to regret not buying one when I had the chance.

Either that or I'll sit in one for the first time, hate it and bin the whole idea.
