Perth - What Cheap Car (sub-$8k)

[Progressive]

Need a cheap car in Perth for doing the shopping and weekends away. Totally open to suggestions. Only criteria is less than ten years old, not a fuel guzzler and small enough for the wife to park. Liked the idea of an SUV, but which one? I've never considered these before.

Viewed a Honda CRV earlier today which was excellent, but the air con had given up. Google suggests that it is likely an expensive (and common) fault.

Any help or suggestions?
