I was hoping they were going to be at Brisbane motor show - not so - bummer
The bright yellow Hummer H3 looks pretty interesting, though the one at the show was LHD.
With the diesel, just remember that at crawl speed the diesel consumption can go up by 10 or 15%. The petrol can go up by double or more. This is where the diesels come into their own - spend a day slugging through bush tracks, mud, sand dunes and the such and you'll really love your diesel
.
If your just cruising the bitumen, yeah, it's hard to justify diesel sometimes.
