5. Cadillac Fleetwood Castilian Estate
In the mid-70s, station wagons were limited to suburban families and small businesses. But the Cadillac marketing team thought it would be cool to offer a super-luxury long roof. They based it on their biggest and most expensive model, the Fleetwood, and cash in on the extravagant body style and unusual combination.

They named the finished product the Castilian. It was a massive station wagon they built on Cadillac’s biggest platform, which they equipped with their biggest 500 CID V8 engine. Customers could order those limited production models through a Cadillac dealer. However, CoachWorks LTD built and delivered them to their customers.
