Grey market vehicles comprise a majority of cars in the national fleet. These secondhand imports have achieved 'normal' status and are used and serviced without comment throughout society. A huge industry servicing and supplying parts for these vehicles has developed. After years of trying to stop grey imports the car companies themselves have become involved, importing in competition with their own new models and providing owners with spare part and repair services. Russia and many African countries, albeit not South Africa where second-hand car imports are illegal, import large quantities of secondhand vehicles from Japan and Singapore.
