Peter, the 1952/3 4/4 frame in the factory museum is very similar to the current frame apart from the rear end style....and not treated of course!
I've always fancied a TC. It certainly can't be compared to a modern Morgan but it would be just the thing to drive over to Shelsley for the breakfasts and race meetings!
I do also have a strong hankering after an MGA Coupe. I very nearly bought one three years ago...a couple of days pondering over it and I lost it!
