I have recently bought a 2007 Sahara with Gas Injection on the twin turbo Diesel. It seems to have more power and torque than other 200's I have driven but need to do a time test or direct comparison with a standard 200. It was on it when I bought it and the fella paid $6,500 afew years back. A 26litre tank of gas lasts 1,500km which is close to the range of the 270 litres of diesel!
