Well that's an option that's never occurred to me. I didn't figure seat covers would make much difference comfort-wise, being as they're...a cover...for the seat. The clazzio seat covers really made that much of a difference?
(I'm really glad you mentioned that -- I was half resigned to the thought of trolling the area salvage yards.)
My bum doesn't much care what it's sitting on, I love my Insight as it is, but then I got married several years ago and my ears have gotten progressively more unhappy with every long car ride.
