I forgot to answer Donna's previous question about bringing in her Disco into Hong Kong. Oops, soz....
Personally I wouldn't, unless the plan was to ship the car back, to the UK, upon repatriating, as it will get punished for being a private import if put on the used car market here, over a HK version.
The Discovery is a Euro 4 or 5 diesel, and are sold in Hong Kong as a 4 wheel drive, so they are legally allowed to be sold/imported into the HKSAR. Only diesel passenger cars ( sedans ) were previously banned.
Also from this year ( 2010 ) it is now legal to buy brand NEW EURO 5 diesel passenger cars, ( FINALLY ! ) which is a major bonus.
Also as a rule of thumb. Only cars that are rare, are in huge demand ( like Nissans GTR was for a little while ) which are hard hard to get locally, that have some classic car status, like a 1988 Bentley Continental convertible, or some odd ball classic Italian exotic, then it' s worth importing it into HK with the intention of making a profit.
If your car in the UK, is as common as muck here, you will lose money, on the used car market against the locally authorised versions.
