Identify Wheels?

I am on a never ending, it seems, search to indentify the type of wheels that came with my car. They are definatly not stock. They are also missing their center caps. I would LOVE to know what brand these suckers are so I can find the right center caps for them. If you can help me out..I'll love you forever. I put a picture up of them in my myspace account. You might have to register to view it, but its free.

what kind of car did it come off of? What year and tire size do you have?

I have no IDEA what they came off of. When i bought my avenger they were already on it, they're 17s ( i believe, really not good with wheels sizes. haha. I'm a woman gimme a break. ) They almost look like they belong on a lincoln or something like that. I just really need to find center caps for them.
