Sweet I know my driver side is bad it's got a greenish tent to it like its just worn out it was like that when I got it I know I would have never get like that but lots of ppl tell me use like a saddle soap / conditioner
Try leather CPR I used it in my KR f150 bought use and the seats showed wear. After a few treatments they looked like new. Ford has some stuff too never tried it but heard good stuff about it.
You could clean them with Lexol cleaner then Lexol oil the heel out of them. The color will come back, although not like what the link shows, but fairly decent. Then a couple coats of Bick 4.
But if you were close to the guy in the link I would go to him. That would be money well spent. IMO
