Subaru mocked the Chicken Tax with the BRAT. The seats had to stay in until the warranty ran out. Roll bar optional, but they did provide four grab handles to keep the passengers in the bed.
I had a manager with two unruly teenagers. When she needed a car, I suggested a BRAT and let them compete for the indoor shotgun seat.
