Can one play a musical tune using car parts as instruments? Well if anyone can it would be James Morrison! On this weeks' episode that is the challenge set by Steve and Warren to James. Does he complete it? Is it really a musical tune? You will have to watch and see! This week sees multiple road tests with the guys checking out the new Nissan 370Z and Steve riding around on the "Rolls Royce" of lawnmowers. You will not believe how much this lawnmower cost! But for all the dollars Steve's lawnmower costs, can Warren build one that is faster than Steve's and costs less than $4,000? Man that's lots of dollars on something just to mow the grass! All in all it adds up to one great duel in a paddock laden with grass. James also gets a trip to Los Angeles to check out the Australian built Pointiac G8 GXP. This is one car where the engine and gear box arrive in Australia and we wrap the body on it and send it right back to the Americans. Well that's free trade for you!
