Buick's GS400 series must be the best-kept secret in the youth/performance market ? though undoubtedly it was not planed that way it is just the way things turned out?Pleasant is a good adjective for describing the GS400. From its vinyl interior to the clean-lined exterior it has a pleasing aspect. Its performance in virtually all facets of motoring is most pleasing to the enthusiastic driver. January 1967 Car Life Magazine
