The first car rental firm opened in Shanghai in 1992 and now 12 car rental players are in the game, with more than 11,500 cars in their books.

The largest player — Shanghai Bashi Tourism Car Rental Center offers a wide variety of choices: deluxe sedans, minivans, station wagons, coaches, Santana sedans are favored by most people.

Firms can attract enough customers for 70 percent of their cars every month. This figure shoots up during holiday seasons like National Day, Labor Day and New Year’s Day, with some recording 100 percent rental.
