Porsche 993

The last air-cooled 911 is the car that defines what a Porsche "should" feel like. The flat-six's mechanical symphony, the hydraulic steering's telepathic feedback, the way the rear end comes alive under hard braking — the 993 delivered sensations that no water-cooled 911 has fully replicated. When Porsche switched to the 996 in 1998, purists mourned. Now a 993 Turbo commands $250,000+, and even base Carreras trade for $80,000-120,000. The air-cooled tax is real, and the 993 is its apex.
