Welcome to TM Bill, I'm sure others will be along in a minute as well. I am certainly in a position to answer some of your questions.
I have a bit of car history involving post war sports cars from my early driving days in the '60's, as well as a string of Caterham Sevens over the last 25 years. Like you, I now like the reliability of a modern car with the classic looks and character of an older car. I feel that a 'sports car' should be basic, light, fast, a little noisy and fun, so 2 seaters like the Miata/MX5, Merc SLK and even Porsche Boxters and 911s don't do it for me, they are just 2 seaters!
You have obviously got the hang of various reliability issues? I have recently bought my second M3W, and whilst there are some definite improvements, they have not solved the bump steer yet. My first car has so little bevel drive noise that it was never an issue, the new one is louder, though not enough to need earplugs, and I gather that as the gears wear in, the noise will reduce. There is also the option of using sound insulation around it. I would be interested in whether the bevel box whine actually does get less after a few hundred miles?
The bump steer spoils a good drive, but the car is just so much fun, that it is not the end of the world, just a little annoying, and Morgan tell people that it is part of the character of the car and must be accepted. Obviously I think that is a cop out, but I believe they are working on it, though from what I've heard recently, it may not be possible to retro fit any improvements free. Other than that, the car is getting better the more they build, maybe by the time yours comes through it will be perfect? Oh, sorry I forgot, it's a Morgan and built by hand!
With the Superdry, like all 'limited' editions, I think it is mainly to earn more money for Morgan, [and there is nothing wrong with that, if they didn't make a profit, they wouldn't be able to make cars any more], but there is very little on the car that cannot be done after taking delivery with the use of a good paint shop and a computer graphics company, and a lot cheaper too. However that is my personal opinion and many would rather order the factory car, you have to make up your mind which you would do.
As for dealers etc, you will have to wait and see what local opinions are.
Best of luck, and best to do it sooner rather than later.
