Ctrip's service is pretty good. They have a same-day car rental group where you can consult and help with any navigation questions. You'll need to ask the front desk for details. There's no deposit required, and no extra fees. The manual transmission car performs well, making it inconspicuous and less susceptible to theft. Picking up and returning the car at the train station, airport, or other locations isn't too expensive and is quite convenient. Just remember to fill up the tank when you return the car.
