About the Buick Century
The fourth-generation Buick Century arrived in 1978 as part of GM's massive downsizing programme, shedding nearly 30 centimetres in length compared to its predecessor. The 1979 model year is notable for its 'aeroback' fastback styling on coupes and sedans, a controversial design choice intended to improve efficiency that was eventually replaced by a traditional notchback. Under the bonnet, the 3.8-litre V6 became the hallmark of this era, offering a balance of reliability and fuel economy during the second oil crisis. While not a performance car, it represents a pivotal moment in American automotive history when luxury brands pivoted toward smaller, more efficient platforms.

Buick Century fun facts
- The 3.8-litre V6 in this car is the ancestor of the famous Series II 3800, one of the most produced and reliable engines in GM history.
- The 'Aeroback' fastback styling was so unpopular with buyers that Buick had to reintroduce a formal notchback roofline for the 1980 model year.
- Despite the downsizing, the 1979 Century offered more interior headroom and legroom than the much larger 1977 model it replaced.
