I personally would be very tempted by the demo. You save yourself a huge wait and really 150km is bugger all. Most demo's car dealers offer people usally have at least 1500km on them.
Ohh and to top it off you are saving $3000 as well! Sounds like a pretty good deal! Provided it's as Ford Grunt said, that is, it has everything you want on it.
