I hate the factory carpet mats. They don't stay in place, the passenger side and rears are always trying to jump out the doors(no hooks like the driver's one). The main reason I wanted aftermarket thick rubber/plastic ones is because my heel wore through the factory mat and started wearing the carpet. Before you know if you have a hole to the floor board, then the paint wears out, then rust. It's happened on every other vehicle I've owned, trying to keep this one nice...
Breathing in and out is good enough for me.
