After owning the 900 for a year and a half, I found out that the passenger seat back does not adjust. For some reason, the knob that adjusts the tilt angle just spins. That was one of the big reasons for driving to Michigan for the free 9000. The interior matches our 900. Unfortunately, the new seat doesn't have a release to allow entry into the back seat, meaning that the kids would have to enter through my door every time. So, while the 9000 seat is a beautiful specimen, I am thinking about selling it instead to someone with a four door ... or no children.
