Volkswagen has been into a difficult period the latest 2 years, after being caught cheating on emissions, but now the automaker is selling cars with diesel engines in U.S. again. Customers lined up to buy two-year-old Volkswagen diesel cars when the automaker unexpectedly resumed sales in April. Many VW customers may still want the fuel efficient diesels — also called TDIs — but the few thousand cars left at dealerships after the automaker resolved its emission-fraud crisis are the last ones the automaker plans to sell in the U.S. One dealership, in Troy, Mich., got five offers for every car it had. VW dealers had about 11,000 unsold 2015 model year diesels in stock when the U.S. government told them to halt sales in September 2015 because the company cheated on emissions tests. Volkswagen has paid billions of dollars in fines to date and faces further investigations in the U.S. and around the world.
