This 2015 Porsche 911 GT3 (991.1) retains its original factory-installed F-code engine, rather than a later G-code warranty replacement. For collectors and enthusiasts, this is a key value point—preserving the car’s as-delivered originality, uninterrupted service history, and long-term desirability. An original engine avoids the stigma of prior engine failure and reflects careful ownership, proper maintenance, and a clean mechanical story, making it more attractive to purists and stronger in resale value.
