Buick Luxus specs: 1973-1977

The Buick Century Luxus, or just plain Luxus as alot of folks call them was only around for 1973 and 1974 as an A-body. It was replaced the next year with Century Custom. Luxus slotted in between the base Century and Regal. Coupes had the formal roof and the car was also available as a four door sedan or five door station wagon. You can tell a Luxus from afar by looking for the small emblem underneath the ‘Century’ on the fenders.
