I've always liked Focuses. I like the older ones a lot, 02-03, especially the SVT.
As for rims, I wouldn't get anything too over the top, seeing as it is an otherwise unmodded Focus. Get something that looks like it could be factory made.
The 2003 SVT Focus wheels would probably look pretty cool on there.

I also always liked the rims that came on the older Acura Integras. They'd look good on there probably.

Just a few ideas.
They also make them in white, black, and chrome.
