You posted: Two aspects.
First, I wanted to keep the back interior of the car for aesthetics. That'll probably change as I move onward with the car. It's only 6 months old with 3100 miles (of which around a third are track) so I'm not quite ready to start yanking out and shelving stuff.
I know I can loose quite a bit of weight removing it but I don't care to spend close to 2K for a sheet of press board covered in Ozite for the "back seat delete".
I'm capable of doing the seat delete on my own, just don't have the time/desire to spend on it right now - that's all taken up with my present (5 year long) project in the pic below. Once it's done I'll probably direct more attention to the M2.
