A few thoughts on your new wagon aka Estate

Seriously lube all the rear seat mechanism, especially in top of wheel well and exercise them frequently.

When you lift the red center latch of the seat cushion [what you butt sits on], you'll be able to slide the seat cushion up and gain about 6" storage space. When you reinstall the seat, slide it down "evenly" on the two pins. The pins are white metal and can snap. Also when the seat back is down [for additional storage] the holes in the top edge should line up with the pins.

Wagons are prone to rust along the bottom of the rear windows. Peel back the rubber on the inside to inspect.

I know 94's & 95's wagons have [rear only] self leveling suspension aka SLS. It's a great feature when it works. If you have it, do a search to learn maintenance and repair of the system.

They handle and perform wonderfully and haul an amazing amount of stuff. Enjoy your wagon.
