Yikes! Obviously a nice wagon, and kept garaged, but a B-I-N of $7,000! I'm hoping his reserve is closer to $4,500, because that's about what it's worth.
It's a wagon in my book. Roughly a third of the length is front end, a third doors, and a third from the top of the C pillar back, room to store a spare between the rear wheel opening and the rear of the car. Lots of wagons had hatchbacks from the 70's up, the hatchbacks that claim to be wagons are way too short behind the rear wheels and have no load floor to speak of. I don't like hatchback wagons much, can't hang long stuff out the back on top of the tailgate and tie down the rear window.
Even $4500 would be stretching it. These A-bodies just don't seem to bring much money even when in pristine shape.
