lets face it as a car theyre crap, they were crap in their day and rose tinted specs don't make them any better
but as a low mileage original collectors item and money making bargain its a great find. id do no more than getting it running reliably and cleaning it up a bit then look to see about getting it valued via an owners/enthusiasts club that theres bound to be for them. such a low mileage original examples bound to fetch several times what you've paid for it.
a quick ebay search shows a similar 45000 miler up for £3500.
