Can you lease a car in Australia like you can in the US? I don't see any current offers on the websites of auto manufacturers for AUS, so no telling if it's possible.

Finance in Australia tends to be along the lines of lease purchase - or novated leases in the case of vehicles used for business purposes.

For example:

http://www.leaseplan.com.au/

There are rumours that this week's Federal Budget may contain some measures to discourage ownership of larger motor vehicles, so maybe also keep a watch on the 2008 Budget announcements:

Best regards.
