The 06 just on the tail/head lights alone. The 06 looks better inside and out and you can source a set of Brembo calipers and rotors.... And the sport front bumper is hot...

 

You can source headlights and taillights too. And for much cheaper than a set of brembos if you look hard enough.

 

If you look around the 06/07 headlight are not as easy to find... And it seem the OP is looking at an 06 already.. Plus let's not forget the uprev engine has more ponies in stock form. Yeah it uses oil. So what most high performance cars do.

 

The 04 also has less torque, and let's not forget that torque is the important number. And I burn no oil.

I got my 06 headlights for $250 with trade.

 

There are wizards on this forum. He just mentioned every problem my car ever had. My car is coming up to 80K soon.

 

I sell new compression rods with polyurethane Energy bushings preinstalled.. Just sayin.
