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."

EA839

"Audi-derived V6TT. Strong, refined. Coolant transfer tube is Achilles heel. Porsche tax on repairs."
