Hey dragin, I actually rode in one of the old Geely taxis about 4 years ago, but not in Chengdu. Old Geelys, Xialis, etc. are still used in the smaller towns, at least in Guangxi province. ALSO, in the smaller towns you are now seeing 3 wheel motorcycles with QQ bodies over it (or Spark, Changhe Ideal, even a poor ripoff of the Toyota Prius)!! These are 150-175cc water cooled motorcycle engines, for their size they can carry 4 people at around 40-50kph top speed.......not too bad really! I rode in a couple of these in the last several weeks in a little town called Xing An in northern Guangxi - almost ALL of the taxis in the town are these QQ style 3 wheel motorcycles! They are buzzy, noisy and kind of cramped - and they are a HELL of a lot of fun to ride in!
Here's a pic of one, enjoy!!
