A lot of these observations are purely assumptions, and the condition can only assessed by a physical examination if it. Over the years, having bought many classic Triumphs, some of which had been laid up and 'off the road' for a good number of years, it really is dependent on how it has been stored, and the condition / circumstances when stored
If I was in the market for a good 3.2 Elite, then I would definately go and see it (with a code reader) and assess it from there.
I have been to look at many classic Triumphs that have been stored for a long long time - some I have immediately walked away from, some were just destined to be broken for parts, but some I have been pleasantly surprised at.
Anyone who can dismiss it without physically seeing it isn't genuinely interested in it.
