You can look out for AutoART. They do made some very high-detailed die-cast scale model cars including some 1:18 scale JGTC cars... If you can find a hobby shop near you then you should be able to find one or otherwise the most alternative way is through online shopping
If you're interested in a smaller scale like 1:64 (similar size to Hot Wheels cars), Kyosho do made them with an unexceptional details.
