I don't think having Jensen-Healey as a separate make from Jensen is a good idea (even if strictly "correct"). It makes it more easily lost if not part of Jensen, and will create problems if and when we get any examples of the Jensen GT which is very much the Healey's younger brother but never had a Healey name reference. So I think we should stick to Jensen as make and Healey as model - it's not "wrong" (the manufacturer was still Jensen Motors) and is much less confusing for actual usage.

I suspect Nash-Healey as make may cause similar usage problems, although not really knowledgeable enough to push that case either way.
