What are the differences between the '03 and '04, if any? I am looking to do some modifications to my '04 but all the websites say 99-03. I know the differences will be small if there are any at all. I think all these websites just haven't updated to show '04 still. Mostly changing my interior (don't want to mess with the warranty) but I like to shop to find sale stuff for later install.

They are exactly the same.

The difference is 1.

The difference between 03 and 04 is 1.

Just trying to help. lol lol


Seriously though, 2003 and 2004 are exactly the same. And yeah, the reason is because alot of websites are slow at updating for new model years

some mods are different though....example

DHP...only for 99-02...due to pc differences...just be careful

but most everything is the same...all the mods from my 00 went right onto the 03

Same car, you'll have no problem with '03 mods, I have a few mods sold to me as '03 mods. I think the only difference I have notice is at some point pontiac decided not to badge the doors, does anyone know what year that was? And one year the lock came off the glove compartment. But who cares about those two, most of us have mp3 players :)

If you want one, call/email DHP they have one for '03 and '04, I was thinking about it, but decided against because of all that re-learn stuff.

edit: Most of the companies are more than happy to alleviate your worries, just ask them if it is compatible.
