I'll second the recommendation for Wet Okole. I have (soon had) a set on my Insight for over 100k miles. They fit GREAT.
I think there's still some pics of the seat covers installed on my Insight on my website in the Insight Gallery:

Not sure if I'm going to get them for my HCH - the interior seems a whole lot more durable than the Insight's - plus the blue interior should hide dirt and wear better.
