Japanese used cars are worth for anybody regardless their levels of life financially. The production of various cars of different capacity in terms of fuel consumption (Low to high CCs) attracted people of all level of life; the high class, middle and lower classes like me. For instance right now I am using a Toyota Vitz with 990cc which is very affordable for my personal trips in and outside town.
The cars from Japan are the best according to my understanding and the experience of using used vehicles from Japan. By low cc means protecting environment and Minimal pollution.
