I know of a white 6TL up here in Scotland with a full sunroof, but the owner won't sell it. Last time I saw it the condition was rather good, considering it's laying outside, but what it's like now I have no idea. It was missing it's carb for some reason, but complete apart from that. No idea what the reg number is, but if I see it again I'll take note, assuming it hasn't gone to the crusher.
