All major changes were made by the 2004 model year, as far as I know. After that, a few minor things that were options became standard (or added to a package) but none of them were very significant. If you want to get a newer one for lower mileage, better condition, and less headaches, that makes sense. But it'll be pretty much the exact same car.
