tip: buy the brands which depreciate the fastest here, like Opel, Renault, Ford. A few years back I bought a 1997 Opel Vectra 2.0L 16V auto for HK$18000, a great drive and lots of toys ( heated front seats , steering wheel controlled audio, sunroof, auto windows) the downside was that the aircon had problems almost every year. And there were many minor defects. But for the same size/class japanese car I would had to pay like HK$80000. The 2nd hand 2001 Ford Mondeo 2.0L look very nice, but they still cost around HK$35000. A few months back I traded in my old Opel for a new 2nd hand Opel Vectra. ( yeah I'm loyal to this brand) But this one costed HK$100000. But I did got HK$30000(which actually was HK$10000 worth) for my old one, I only got this price because I was trading it in for another.
