Not sure when it changed but they changed the front end/steering and added larger wheels and tires. The handling is WAY better than my '01. Some where along the line they went to the 5 speed tranny which I find really nice. It shifs down with only moderate pressure on gas pedal. I also got the night vision, which wa the only option.
I tow a jet ski alot and I do not like how the new hitch works whre is come out of the middel of the bumper rather than under it. Other than that I love the unit.
