found a private party X5 a few miles from my home. fully loaded but has the rear-dvd set up, which I've heard nothing but bad things about it. I hear it gets in the way all the time, and to be honest, think it looks pretty cheesy in an $80k car. is this removable?

also, a dealer told me they could CPO a car they have for sale for $2,200, can I buy private party and then CPO the car? I put 25-30k miles a year on the car, definitely worth $2,200 for the longer warranty.
