The decision to stay stock or not is mostly dependent on personal preference. For me, the condition of the truck makes a difference. A truck that's already been heavily modified or badly tattered is much easier to continue changing. The BMW seats seem to fit the existing style better than the other options I've seen. They are thinner and don't look like overfluffed Lazy Boys.
Function matters too. For some, comfort is everything; soft, heated, electric trim.
A few months back a Mudder put PT Cruiser seats in his 60. They didn't look bad. (If you can get over putting PT parts in your Cruiser.) ;p
These are the $OR cushions under original fabric.
