Modified 1955 Pontiac Chieftain Sells for $35,550 on Bring a Trailer
Refreshed and Reimagined
We were proud to represent this thoughtfully modified 1955 Pontiac Chieftain, which sold for $35,550 on Bring a Trailer—a compelling result that reflects continued enthusiasm for mid-century Americana reimagined with modern usability in mind.
Finished in a rich red and black two-tone, this two-door sedan has been comprehensively refurbished and upgraded, with a focus on enhancing drivability without diluting its 1950s character. The factory powertrain was replaced with a 350ci V8 and 700R4 four-speed automatic transmission, bringing effortless highway capability to a chassis originally built for the era of two-lane cruising.
Balanced Modifications with Purpose
Performance upgrades include power-assisted front disc brakes, electric power steering, an aluminum radiator, and staggered Coys wheels. Inside, power-adjustable bucket seats, a custom console, tilt column, air conditioning, and Alpine audio signal a clear intent: period style, present-day comfort.
Modern Heritage
Originally introduced as Pontiac’s bridge into the modern V8 era, the 1955 Chieftain marked a design and engineering turning point for the brand. This example honors that moment of transition with mechanical and aesthetic updates that respect its lineage while refreshing its relevance.
Its final hammer price underscores a steady demand for classics that blend authentic presentation with functional upgrades—particularly when curated and presented with care.
