Keep your eyes peeled on the
Asiaxpat used cars for sale section of the classifieds, you get the odd bargain in there from time to time.
There was 1994 BMW 5speed auto 520i, that had service history, and previously expat owned, for $10,000hkd inc 6 months worth of road tax/registration, which alone is worth close enough to $3,000. Would have been worth a look, as it sounded quiet good-honest and if my 90 535i that traveled 260,000kms without incident back home, is anything to go by these cars are generally pretty good, if they are cared for by the previous owner.
Anyway, for $10,000 that would have done the job pretty well, I think.
