When the day arrives of stiff joints and so on, I will be sad to part with my Trads, but I would go for something less quirky than a CX. Maybe a Merc convertible, if I could find one with a manual box.
Funny isn't it. If the first Plus Six was introduced with a manual box and spare, I would 80% certain to have traded both Trads for one. But the years have made me realise that I would have regretted jumping in, even though the first incarnations are closest to the Trads.
