I purchased a set of tiger looking covers for my granddaughters 98. Nothing fancy, around $150 if I recall, fit like gloves, have held up incredibly well. Seat Covers Online I think, I can confirm Monday if you are interested.
Having owned and installed various covers in various materials (sheepskin, Marathon's corduroy, neoprene, etc.) at various price points, I can positively state that installation is the key. For example, if I'm covering old worn seats, I always spray the covers and seat faces with a light covering of 3M spray adhesive before pulling the covers as tightly as possible. I also fashion and use additional holding straps, even when installing the cover on a brand new car.
Finally, realize two things 1. The factory covers are more often than not just covers expertly cut and installed and 2. Nearly every town has a backwater trim shop (backwater meaning in a garage or barn behind the guy's house, no marketing, not fancy, known only to local car guys) that will recover a couple of buckets for less than you think.
