About the 1978 Porsche 911 SC Targa

The SC Targa represents the sweet spot of G-body 911 ownership, reliable, analog, and unmistakably '80s cool. Built during Porsche's recovery from the malaise era, the SC's 3.0-liter flat-six delivered a healthy 204 horsepower through a crisp five-speed manual. The removable Targa bar offered open-air thrills while maintaining structural rigidity that convertibles couldn't match. Ferdinand Alexander Porsche's timeless silhouette reached full maturity here, with impact bumpers finally integrated seamlessly into the design. These cars have shed their 'entry-level classic' reputation as collectors recognize the SC's perfect balance of usability and character. Clean examples with original Fuchs wheels and intact interiors command serious money, especially in desirable colors like Guards Red or Grand Prix White.
