The 2007 model has 22 or 23 more horsepower (cant remember which one it was) than then the 2006 model which I feel really made a difference when i drove both of them. Also 2007 has 3.7 litres rather than the '06 3.5 litres. Othar than that the car is just about the same car. However if your looking for that Green color they stopped making it for 2007 also same story with the Superior Blue, now its a midnight blue instead. I my self got the 2007 one, it just came in today... cant pick it up till tommorow though
Either way you cant go wrong.
