We put less than $5k on a SsangYong Rexton auto, turbo diesel,142 000k's, 6 months rego, nudge bar and towbar.
Up to 100kph highway running it gets around 8l/100k, smooth, semi-roomy, comfortable, 7 seater that all folds flat for sleeping, 4x4 for rough or muddy tracks, and styled by Giorgietto Giugiaro's Italdesign studio.(I think that means it has been hit by a bloody big European ugly stick)
For a Korean Mercedes, it has been faultless for over a year and 30 000k so far.
Parts appear to be available but not in remote areas, and a few days for delivery could be needed.
I would not hesitate to take it around Oz.
