Allan,
Welcome to the site, and I'm sure you'll have plenty of fun when you car arrives, mine managed to knock up 2000 miles over last winter.
Now I don't want to be the bearer of bad news but if you've been lurking on the forum for any time you may have discovered the Morgan delivery dates are flexible. Mine was due October but arrived in November just added to the anticipation.
Regarding your colour choice, it'll be find and sounds go as long as you haven't matched it a pink interior. Anyhow it couldn't have been more frightening than mine.
