Bentley cars are on sale at a showroom of a dealership at 'Barvikha luxury village' shopping mall outside Moscow, Russia, February 1, 2016. As Russia wrestles with an economic crisis, more and more Porsches and Rolls-Royces are appearing on its roads. It seems something of a paradox; while mass-market car sales in the country have tumbled along with the rouble and oil prices, one area is bucking the trend - luxury cars.
