Try the Toyota Alphard, I have seen loads of these around HK.
There is a classified section on this website as well, always worth a look: Automobiles (Owners) | Hong Kong Free Classifieds | AsiaXPAT.com
In my own experience I spent a few months checking out the second hand market, visiting some dodgy malls and meeting dealers in dark car parks, so in the end I bought a brand new car. VW were doing a interest free finance deal and offering a discount on the list price, after all the messing around with dealers and 2nd hand sellers who were economical with the truth, a new car was really the only viable option. HK is very harsh on cars, with a new car you'll get a lot less worry and stress, and even though people have gone through the numbers, the stress and time taken to deal with such things isn't taken into account.
Good luck with your search.
