Jap imports are pretty sweet and in very good nick and worth every penny, good climate, no sandy weather and heat and usually pretty well looked after. I've bought jap imports that looked like they had just rolled of a factory floor, well majority of them are like this, most of them have a Japanese auction sheet and there are tons of sites where you can learn to decode them and thats pretty much a very decent pre inspection sheet, if its not available there is not much to fret here.
Like this example, is a 4.5 out of a total of 6, 6 is a brand new vehicle.

But be aware some people and a shady dealer or two sometimes try to sell a jap import thats already been registered here in the UAE, driven here for a year and two and then been tried to pass off as a fresh import, but they are pretty easy to spot and don't have custom papers but rather local papers.
Just an example video here, and those who love JDM crap this is an awesome channel featuring a lot of jap domestics
