I'm planning an overland expedition tour by end of August 2013. I will start from Turkey and across İran, Türkmenistan, Uzbekistan, Kazakhstan, Russia, Mongolia and finish my trip in Vladivostok in Russia. I have Suzuki Grand Vitara 2.0 2005 model. I want to change my car and buy a new car. My first choice is Land Cruiser VX 100 2003 or 2004 model. I would like to know whic kind of engine is more adequate for this trip: diesel or gasoline. Thanks for your recommendations.
