I don't have a Sonata, but I was looking around on Evofusion and found a few that look pretty nice. Check them out here.

 

hmmm..those are pretty nice

 

I was expecting something REALLY ricy, but that doesn't look all that bad. I especially like the spoiler.

Will that fit the 05? It says only 2002-2004, but the website may be out of date (like that ever happens).

05SG

 

It should fit as long as the '04 and '05 models have the same body without any restyles. Like I said, I don't own a Sonata, so I really don't know much about them.

 

im sure that if you contact the company, they will know for sure if itll fit.
