Wow, looks like it's missing the turret.
Seriously, cool car. I think that's one of those wagons with one of those two-way tailgates, if I remember correctly. It either folds out like a tailgate, or opens like a car door. I believe you can also turn the trunk key and watch the rear window drop into the tailgate. These cars are attention getters at cruise nights. Most younger people grew up in SUV's, and they have no idea that most familes, back in the 70's, had station wagons. This Olds, and the big Buick Estate Wagon, were the most luxurious "family trucksters" in the GM lineup at the time.
