Many used cars come from Singapore or Japan, and are sold in other countries around the world, including United Kingdom, Russia and New Zealand. Japan and Singapore both have strict laws against older cars. The Japanese "Shaken" road-worthiness testing regime, requires progressively more expensive maintenance, involving the replacement of entire vehicle systems, that are unnecessary for safety, year on year, to devalue older cars and promote new cars on their home market that were available for low prices. This makes these well running cars seem reasonably priced, even after transport expenses. There are very few cars in Japan more than five years old.
