Sof-Touch Seat Covers

Whether you are protecting the original interior of your prized car or truck or if you need to cover up previous damage to your vehicle’s interior, your Sof-Touch simulated leather seat covers are guaranteed to fit like a glove

The master craftsmen at Ruff Tuff Products do not mass-produce these simulated leather seat covers. Each simulated leather seat cover is designed, cut, and stitched to meet the specifications of your vehicle right here in the United States -- guaranteeing a perfect fit every time.
This sounds to me like the way to go, your cost is cheaper and you do not have to take the curruent fabric off your seats. I would look into the guarantee but it sounds like if you don't like the look you can send them back.
