My dad always had a station wagon. The one I remember the most and drove for hunting and fishing was a Kingswood Estate - probably 1974 or so. I know it had the 454 engine in it. Had the clam shell back end.
Fit a 4x8 sheet of plywood, or sleep me and a buddy and our gear.
The youtube Matt’s Offroad Recovery just did the “Cannon Ball Run” using a 1993 Buick Roadmaster that he bought for $4,000 when he got to the east coast. (”It’s always fun to do the test drive after you buy the car”.) They named it “Aunt Edna”.

My mom’s had a 454 too. You could literally watch the gas gauge move.
I watched Matt’s cannonball. I’m starting to get the bug.
