Hi there -

The best 4wd models for desert work are:

* Toyota FJ
* Toyota Landcruiser
* Toyota Prado

* Nissan Patrol

* Jeep Wrangler
* All other Jeeps except for the crossover model - can't remember the name

Land Rover Discovery

I think the Hummers are good as well

When i lived here in the past i had a Jeep Grand Cherokee and loved it - it went very well in the desert (you must drop the tyres to at least 15 psi), was still comfortable on long trips and had a great sound system!

I have just moved here and am looking to get another Jeep as i think they have a good price/performance ratio. The Toyotas and Patrol are the best for resale value however and are probably more reliable than the Jeeps.

To the OPs post i would add 4x4 motors and Off-road motors to the list - both seem to have a pretty good rep among the western expats.

Have fun!
