The G-Series 911, produced from 1974 to 1989, is one of the longest-running and most recognizable generations of Porsche's flagship sports car. Defined by its impact bumpers, a change mandated by US safety regulations, the G-Body retained the classic 911 silhouette while evolving mechanically. Early cars used a 2.7L flat-six, which was replaced by the more reliable 3.0L in the 911 SC (Super Carrera) in 1978, and later the 3.2L in the Carrera from 1984.
Collectors appreciate the G-Body for its direct, analog driving feel combined with improvements in reliability and usability over earlier 911s. Models from 1976 onward feature a galvanized chassis, offering much better rust resistance. The lineup also includes the iconic 930 Turbo, Targa, and Cabriolet variants, providing a wide range of choices. It's a highly usable classic that's easy to maintain and has a massive support network of specialists and parts suppliers.
The market for G-Body 911s is mature and stable. With an average sale price around $62,000, they remain more accessible than early long-hood models. Prices are heavily influenced by model, mileage, and condition. The later 3.2 Carrera models, especially with the desirable G50 transmission (1987-1989), command a premium, while high-mileage SCs and Targas represent the more affordable end of the market.
Buying Tips
- Check for rust in the kidney bowls, rocker panels, and around the front and rear windows, especially on Targas and pre-1976 cars.
- The original 2.7L engines can suffer from pulled head studs. The 3.0L SC and 3.2L Carrera engines are known for their durability, but check for oil leaks from the oil return tubes and thermostat.
- The 915 gearbox requires a deliberate shift; test for worn synchros by shifting into 1st and 2nd gear. The G50 gearbox, found in 1987-1989 Carreras, is stronger and more valuable.
- A comprehensive service history is critical. It validates mileage and shows a history of proper maintenance, which significantly impacts value.
- Many cars have been modified or 'backdated' to look like earlier models. Assess the quality of modifications, as they can either add or detract from the car's value.
Prices range from under $40,000 for drivers and project cars to over $177,000 for exceptional Turbo or late-model Carrera examples.
