Starting in 1970, Buick proved that you could have the very best in luxuries and all the power of a muscle car. Unfortunately, less than 7K GS 455s were made and of those only 1040 were convertibles equipped with a TH400. This rarity means finding one today could prove to be difficult. On the other hand, the model was based on one of Buick’s most popular luxury car models, which opens the door for aftermarket clones and tributes.
