I think my next purchase will be some new seats since i can't drive more then 20 minutes straight without my ass hurting in my leather seats. Post pictures of your aftermarket seats with names and prices!
Instead of thinking about new seats, why don't you invest in some good quality genuine sheepskins.
They are extremely comfortable, and you don't stick to them like you do when sitting on the leather.
Plus, they are warm in winter, and comfortable in summer.
I put mine in just because I don't like sitting on leather.
