Mercury Grand Marquis Panther Platform (1998-2011)

1998–2011 · Panther · sedan

Final two generations of the Mercury Grand Marquis (3rd gen 1998-2002 and 4th gen 2003-2011) — both on the Ford Panther body-on-frame platform shared with the Crown Victoria and Lincoln Town Car. 4.6L 2V Modular V8, 4-speed AOD-E / 4R70W / 4R75W automatic, rear-wheel drive. The platform that defined American police-and-taxi durability for over 30 years.

Watch out: 4.6L 2V plastic intake manifold cracks at the coolant crossover — well-documented universal issue, especially on pre-2002 cars (Ford issued the aluminum-crossover replacement intake as the fix). Rear air suspension on early cars (later switched to coils) leaks. Otherwise extraordinarily durable; many fleet-mileage examples still on the road.
