Buick G-Body
Master Customs concentrates Buick coverage on the Regal and the turbocharged performance lineage that produced the T-Type, Grand National, Turbo T and GNX. Century and other non-performance Buick intermediates remain supporting platform history.
Regal first. Turbo Buicks deepest.
The Buick branch follows the same rule used throughout Master Customs: full reference depth for the cars enthusiasts search, modify and preserve; supporting context for related models that matter mainly for platform history or parts interchange.
Buick Regal
The complete G-body-era Regal guide, from personal-luxury coupe to the turbocharged foundation that became one of the decade’s defining performance platforms.

Related Buick intermediates
Buick used GM intermediate architecture across more than one nameplate, and those cars matter when researching chassis family, component interchange and division history. They do not receive the same stand-alone editorial depth as Regal-based performance cars.
Why the distinction matters
The site remains useful because it is selective. Master Customs is not a generic catalog of every trim level; it is an enthusiast resource with a consistent bias toward performance, modification potential, technical interest and cultural significance.
Master Customs treats period factory literature as the baseline and separates factory configuration from enthusiast modification. Turbo-Regal terminology changed by model year, so a specific car should be verified by VIN, RPO/SPID information, original documentation and drivetrain codes rather than appearance alone.
