Character
M97
"997 Carrera. IMS issue mostly solved in 2006+ (larger bearing). Bore scoring still possible but less common. More refined than M96. DFI on later 997.2 (MA1 series) eliminated IMS entirely."
9A2
"Modern 911 heart. No IMS drama (thats 996/997). Reliable, powerful, expensive to service. Porsche at its best."
