We've had lots of Toyota 4wds (DH gets a new company car evey 9 - 12 months) and we currently have a 200 series Landcruiser. It is a 7 seater and by far the roomiest car we've had! Ours is on petrol, but I've heard diesel is better (cheaper?). We are very happy with it, but it's HUGE! We wouldn't normally have such a big car, but we are going on a 6 week caravanning trip later this year and wanted something that tows well.

My favourite 4wd is the Landcruiser Prado, it is still very roomy, but a bit more comfortable/luxurious than the Landcruiser. It's also really easy to drive and park. Oh, and it has 7 seats.

Good luck deciding!
