The new 2006 are out and they have a bit more options! like exterior temperature gauge and 5 speed auto trans (which I don't really care anyways).
The A/C was a new micron air filter, which is a good idea because it would be easy to clean (many car I have seen including my own over a 5 years period the air duct are full of hair and dust).

Everything else seem the same except some color differences; sunset orange no longer available replace with copper red mica and only on the GT as well as snow white pearl (95$ more than the average paint) and winning blue available on the GS.

The prices are roughly the same, but of course interest rate are higher.
