You try buying a 2002 Model Diesel Prado or Hilux, its dropped about 10% upto 75,000 kms and they get sold within thirty minutes of being put on market.
You try selling a VY Commodore with similar kms and expect to get 30% back on your original outlay for it!
I deal cars part time when I need the cash and the market is hot, right now its not hot!
Stay away from Saab, Mitsubishi 380, Commodore, Audi and any of those hopeless Crewman/Cross 8 things.
New C Class Mercs all day as well as anything Toyota if you want good future resells.
