looks like you ahve no language barrier. even if, many have chinese webpages or collaborators in china websites, my friends all easily booked DOLLAR service in chinese. interestigns they all ahd soem minor problems here, one got a flat tire (and so grateful for ameiricna's samaritan and warm behaviors), the other stopped by a police (also chinese ethnicity!, just a warning).

usually it's 30-80 $ daily depends on car type, of couse it's just basic, after everythign added up, should be 50-100 per day, returnign car at different location costs more. most have no limitations on mileage use, but look out for some small companies who want to cheat a few more bucks from customers, esp foreingers.
