Over the years, the availability and quality of die-cast cars has increased greatly, due to increased exposure via the Internet and tooling methods used. It is now possible to cheaply attain high quality, highly accurate representations of a lot of cars, in particular classic Japanese ones.
A good demonstration of this in the 1:64-72 range is the TOMY Tomica “Limited”. The accuracy and detail of these vehicles is usually quite high.
If you’re interested in what’s currently available new in the “limited” range then visit the TOMY website; Sadly, it’s all in Japanese so unless you can read it, you’re likely out of luck, translation tools will miss most of the site in that it’s mostly images as opposed to standard text, though with a bit of perseverance you should find your way around fairly well.
