Character

M64

"993 Carrera/Turbo. Last air-cooled 911. No IMS (that's M96+). Turbo version hugely reliable. NA version: chain tensioner. Cam chain guide. Simple by Porsche standards. Iconic."

EA839

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