What are Saab Seats Design “Business”?

Hello Saab Kenner, My girlfriend drives a Saab 9000 Turbo from 1992, which still has many parts of the 91er. No matter, that’s not the point, but: An acquaintance has put the flea in her ear that her seating equipment: leather with velour stripes on the sides with seat heating but otherwise only manually adjustable, would have been installed afterwards and the value of the car increased into (immeasurable) ;o). My question to Kenner: Are these seats really in demand and are also called “Business ” when the settings are manual? Thank you. Fukkel
