More to think about.....
I am assuming that when you refer to the A series Xiali for 51,000rmb, you are actually refering to the N3. IN any case, a couple of things to think about....
First of all, what are your NEEDS with the car? Is this going to be a "light use" vehicle (mostly for passenger use, food shopping, work commute, etc.) or more a "heavy use" vehicle (loading lots of heavy things, deliveries, etc.)? If you are leaning more towards heavy use, then I would DEFINTELY go with the Suzuki. More room to carry things, more powerful engine and stronger shocks and suspension. If it is more for "light use" then the Xiali would be the better of your 2 choices................but you MIGHT consider something else.
Have you seen the new Chery QQ6? It is the newest entry in the QQ "family"....within a year or so Chery will have 3 or more cars that are all part the QQ series!! The QQ6 is a bit larger than the Xiali (as well as the regular QQ) and comes with either a 1.1 (same one as in the QQ) or a 1.3 engine (a new design but being used in several Chery models now). The MAIN thing though............Chery is just a higher quality car than the Xiali (in my opinion). Yes, the Xiali will have a toyota engine - but what good will that be if something else is broken on the car????????? I've driven the Xiali N3.......not a bad car, but the transmission is NOT very good and I wasn't all that impressed with the brakes either (and I drove a new one at a Xiali dealer). The amenities offered in the interior are NOT equal compared to the Chery - 2 power windows in the Xiali vs. 4 in the Chery, better quality fit and finish (when I sat in the Xiali I could easliy see defects in how the parts fit together all over the car) in the Chery and I think a BETTER engine (at least comparing the 1.1 engines) in the Chery as well. The QQ6 is a brand new car and just started selling near Shanghai about 2 weeks ago........I would think that it will be in Guangzhou (as well as in Nanning where I live) in about a month. Other models to also consider:
Xiali - the new C1 (a MUCH more modern car than the N3 - they are already starting to build them and we should see them in 2 months or so)
Changan - CV6 (maybe not the right choice for you........about the size of the QQ or a TINY bit bigger).
Chery - S12 (this will actually be the 3rd member of the QQ family....it will be given another name like QQ5 or QQ8 or something like that - also bigger than the original QQ and it should be ready to sell by the early part of 2007).
Shanghai Maple - 205. This car has been sold for a few years now (it used to be known as the Jmstar before Shanghai Maple bought the company). A 1.3 engine and nothing really special - but it IS a good car with decent quality and a GREAT deal for 47,000rmb......and a LOT more room and comfort than the Xiali (check out the air conditioner in the Maple............WOW is it powerful and I know you live in Guangzhou

).
There is also the Geely MR (42,000rmb with a 1.3 engine), the Geely SRV (41,000 with a 1.3 and 45,000 with a 1.5 engine)............but I would REALLY consider the new QQ6. 4 door looks, 5 door flexibility and a great price (46,000 for the basic 1.3 and 52,000 for the top model - which includes air bags, CD changer and also ABS I believe). Good luck and keep us "posted" (no pun intended)!!!!!!!!!
