Thanks for everyone for the good wishes. I'm still undecided what to get but the information given has helped me narrow it down!

What is the issue with the 3.0ltr? I mate from work brought one and the Glow plugs snapped off and well he's up for a new engine. I thought it was a oil related issue?

A 4.2 GQ would be my prime pick, thanks Taslucas for the link. Shows what i can get value for money. Pitty it's across the Tasman :P
