The Buick Skylark started in the mid 1950's as a submodel of the Roadmaster convertible, equipped with all the options available at the time. It included AM radio, power brakes, power windows, and a completely carpeted floor pan. However it wasn't until the 1960's that it gained traction in the market as a compact and then a mid-size family car. The family car image, however, did not necessarily apply to the performance variants of the Skylark like the GS (Gran Sport) models. Very cleverly, for most of the Buick Skylark's life it was very similar to the Cutlass, Chevelle, and LeMans. This made many Buick Skylark parts interchangeable with other GM cars. After a brief hiatus in the mid-70's, a much downsized Skylark would return for its fifth generation. At the time, it wasn't much of a performer - the optional 350ci V8 didn't even come close to putting out 200hp. Subsequent generations fit easily into the economically priced compact market, and sold well alongside the other X-bodies. Fun fact: the first model Skylarks were all convertibles, and even though they included every available option at that time, Buick excluded air conditioning simply because of the body style.
