Model overview
Model description
Pontiac’s lineup was restyled in 1949 by Herman Kaiser along Harley Earl’s guidelines. The cars featured a full-width body and curved two-piece windshield common to Cadillac and Oldsmobile. Two models were built, the Streamliner and Chieftain, and both rode on a 120-inch wheelbase. Both could also be ordered with either a 239-cid six-cylinder L-head engine that made 90 hp, or a 248-cid straight-eight mill that developed 104 hp. Transmissions were the Hydramatic automatic (78%) and three-speed manual.
The Streamliner was Pontiac’s entry-level model. Pontiac Streamliners could be ordered as two-door sedan coupes, four-door fastback sedans, and an eight-passenger station wagon that could come with or without a Di-Noc exterior. DeLuxe trim could be added to any body style, which ultimately amounted to the addition of a full-length side spear and gravel guards to the rear fenders. Unique to the 1949 Streamliner was a sedan delivery body style, of which nearly 2,500 were manufacture. The car was aimed at the fleet market, much like Chevrolet’s sedan delivery, only it offered a V-8 option unlike the Chevy.
The 1950 Pontiac Streamliner was little changed from the previous year, except that the station wagon migrated to the Chieftain model, and the remaining cars wore a bolder grille. The 1951 model year marked the end of the fastback sedan body styles, leaving just a coupe. Options included a big sunvisor and traffic light viewer, seven-tube radio, and Remington auto-home shaver.
As the distinction between the Streamliner and Chieftain was always a subtle one, Pontiac ceased production of the Streamliner following the 1951 model year and opted to instead use differentiating trims within the more recognizable Chieftain nameplate.
Today the Pontiac Streamliner is a true sleeper, much like its Oldsmobile counterpart, in that it is off the radar of most enthusiasts. Pontiac was a top five automaker during this period, however, so cars and parts are fairly easy to source. This fact helps keep cars affordable, and makes the Streamliner a great choice for someone looking to experience early postwar American auto ownership.

Many factors can increase a car's value including excellent condition, exceptional originality, a recent restoration, low mileage, unique provenance, desirable options, popular or unique color choices, and excellent maintenance records. Upgrades and modifications that enhance performance or aesthetics can also add value.
Factors that can decrease a car's value include unusually high mileage, poor maintenance history, visible wear and tear, accidents or damage, title issues, and gaps in ownership history. Additionally, less popular color choices and extensive modifications that don't appeal to a broad audience can reduce value.
Mileage plays a significant role in a classic car’s value. Lower mileage usually increases value because it indicates a higher degree of originality, is rarer, and suggests less wear and tear. However, cars with exceptionally low mileage may also have maintenance needs due to lack of use. Whether someone should pay more for a vehicle with lower miles will depend on how they plan on using it, and the vehicle's specific condition.
The value of modified cars differs widely based on the type and quality of modifications. While some modifications can significantly increase value, especially performance enhancements and high-quality custom work, others may not add much or could even detract from the car’s value if they appeal to only a limited audience.
