edit: Looks nice, clean, unmolested example.
I've seen many cars either imported or awaiting import from Japan and they all look to be above average cf. cars sourced elsewhere. I'm not saying they don't have accidents over there, though I'm almost certain they don't grit the roads.
One thing that seems inbuilt in the national psyche is maintenance and keeping things clean, I guess you'd call it being house-proud. Public spaces are immaculately maintained, as are buildings and this extends to personal cars. Add to that the fact that the biennial equivalent to the MOT test is very much more thorough than our own, and therefore more pricey, (first test after 3 years) that you'll find many cars being sold at 5 and 7 years. Added to that, car tax is high and related to engine size (top band >2.5L iirc) and you need proof of access to/ownership of a parking space before purchase means that the Japanese 2nd hand car market encourages low residuals.
This fact is taken advantage of all over SE Asia, Australia and NZ, and even Russia. The fact that the car is in Japan and isn't viable for inspection would put me off obviously, the fact that it's 'Japanese' wouldn't.
