As the recent purchaser of a car with horrible seats, there may be people upgrading seats for comfort only.
I could order a factory upgrade seat which would cost between $2-3K.
Or just get some regular aftermarket seats for $600.
So I can get "aftermarket" seats just by spending 5 times the money.
I imagine this same scenario can play out on multiple car platforms.
I doubt you are going to see people putting outrageous seats in a "stock" car.
It should be mostly "stockish" looking seats, if your car happened to be an s2000.
If you don't agree with this, it's probably cause your car came with great seats stock.
