1967 Buick GS 400 Convertible: history and background
The 1967 GS 400 Convertible combined Buick’s compact performance-car body with the new 400-cubic-inch V8 specification. Buick’s period release, reproduced by Team Buick, describes the new engine family introduced for the model year. The convertible is a body-specific entry, separate from GS 400 coupes and from the smaller-engine GS 340.

Design and engineering
The open body gives the GS a different presentation from a hardtop muscle car, while retaining the grille and performance-model identity. The 400 designation belongs to the engine specification. It should not be retrospectively applied without explanation to earlier GS cars fitted with Buick’s 401-cubic-inch Nailhead, which came from a different engine family.
Model identity and rarity
The reproduced factory production table gives 2,140 model 44667 convertibles. The licensed photograph’s file title incorrectly says “GS 500”; the image shows a 1967 GS convertible, and Buick’s factory model information establishes the GS 400 convertible scope. The caption records that correction rather than silently repeating a nonexistent factory GS 500 model name.
Collector significance
The car’s significance is the meeting of a new Buick V8 generation and open-top performance motoring. A proper individual-car description should connect the body/model plate, engine identification and option paperwork. The show photograph supplies a clear view of the body and GS presentation; it is not an independent certification of the engine currently installed in that photographed car.

Frequently asked questions
How many convertibles are reported?
The reproduced Buick table gives 2,140 model 44667 GS 400 convertibles for 1967.
Why does the photo source say GS 500?
The source filename contains an incorrect model label. Buick’s 1967 factory information identifies the relevant GS convertible as the GS 400; the correction is disclosed in the caption.
Is the 1967 engine the earlier Nailhead?
No. Buick’s 1967 release describes the new V8 family; the GS 400 should not be treated as an unchanged earlier 401 Nailhead specification.
Why is the GS 400 Convertible included as a rare Buick?
2,140 model 44667 GS 400 convertibles reported for 1967; coupe production excluded. The scope is tied to this specific year, body or original project. It does not confer the same rarity on every car carrying the broader Gran Sport name, and it does not describe how many survive today.
What records help identify an individual GS 400 Convertible?
Begin with the documented year and two-door convertible, model 44667. Read the original model/body identification and surviving factory or collection records together. Record replacement components and restoration work separately. For a concept or racing car, its physical-car provenance is especially important; for an optioned production model, retain the equipment paperwork.
What photographs and credits accompany this profile?
The bundled photograph is retrieved from named Wikimedia Commons file records. Each image has a visible photographer or archive credit, its own licence link and an accurate subject caption. The pictures illustrate the documented model; they do not establish ownership, present condition or every component’s originality.
Sources and photo credits
Production figures retain the scope and qualifications of the named references. Manufacturer and museum records establish project identity; auction and historical model references supply additional body-specific context.
