Customs officials in the Central Asian country have reportedly refused to allow the importation of black vehicles, according to Chrono-tm.org , a Vienna-based opposition website. They haven't given a reason for the decision, but are advising importers to buy white vehicles instead because it's considered a lucky colour, the website says. President Gurbanguly Berdimuhamedov recently started using a convoy of white limousines to travel to public events, and about 160 top-ranking officials, including the heads of the country's main media outlets, promptly followed suit, Russia's RIA Novosti news agency reported in September . The paintwork restrictions are just the latest in a long list of rules, which includes a ban on the importation of coupes, supercars and vehicles with personalised number plates or tinted windows.
