Hi,
I think Op up is 2700 rmb from memory or about 270 Euro. I dont know any car companies as I always get a mini van outside exit 6, just in front of the taxi stand. They charge the same as a cramped santana taxi so I always go for them. If you have light luggage why not take the maglev train at 434 kmh and you will watch the taxis and minivans in your wake.
Cheers!
