Buy or Bye: 2012–2019 Porsche 911 (991) — 991.1 vs 991.2, Huge Difference!

The 2012–2019 Porsche 911 (991) is actually two different cars wearing the same body. The 991.1 (2012–2016) is the last naturally aspirated 911 Carrera Porsche will ever make — and has a documented cylinder bore scoring issue on the 3.8L S models that can destroy the engine. The 991.2 (2017–2019) went twin-turbo, added Apple CarPlay, and is dramatically more reliable. We break down the bore scoring nightmare, why the PCM infotainment on pre-2017 cars is unusable, why the 991.2 is the smart buy, and why the 991 Turbo and GT3 use completely different Mezger-derived engines that are bulletproof collector cars.
