As a buyer I see the Jazz as a safer bet because the owners seem to take good care of them. More of them than not have full service histories and half of those are from Honda. There are obviously less Jazz on the roads than, say ford focus. I don't know if reliability scores take that into account? But overall, I'd guess that they are just well looked after. And seeing how many cars my brother has killed due to ill-treatment, vs the rest of my family. I'd say that probably plays a big part.
