1976 Buick Estate Wagon
Weighing in at more than 5000 pounds, the Estate Wagon was the ultimate family hauler before minivans and SUVs came along. Its cargo area offered 3002 litres of volume, or nearly as much as in a 2017 Buick Enclave. When opened, the tailgate slid into the car’s underbody, while the rear window lifted upwards into the roof. Powered by a 205-hp, 7.5-litre V8.
