It's a once and for all 4WD showdown and to the victor goes the spoils - exclusive dinner party bragging rights. The TGA team are bound for Cairns in north Queensland after starting out in central Australia to settle which 4WD can go the distance.“I have been to a tonne of dinner parties where people have said “My 4WD is good enough to go to Kakadu if I wanted to”. Now everybody knows that they probably never will so we thought we would help with bragging rights for the next party,” said Steve Pizzati.Charlie opts for the luxurious Lexus LX 570, Warren sides with the very capable Range Rover Vogue TDV8, and Steve feels the power of Audi's Q7. It's a 2,400kms test drive for the record books as the lads set out from Alice Springs on a seven night stint under the stars and along the open desert planes - their sanity is sure to be the first victim.Not a fan of being one with nature, Charlie said, “When I was a kid about 12 years old on the family camping holidays I used to lie back at night and look back the stars and think to myself “When I grow up I am going to get really rich so I never have to go camping again”.”Also around the streets of Sydney, Charlie takes the sporty Mercedes SL 63 AMG for a cruise, “A car this stylish can even make a mug like me look good, well not that bad anyway.”Car enthusiast, James Morrison, talks to Top Gear Australia about meeting his wife in a celebrity car race, owning 96 cars and his goal to beat Julia Zemiro on the lap time leader board.
