Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1979 Grand Marquis.
The 1979 Mercury Grand Marquis represents a distinct iteration of the full-size sedan that predates the model’s documented complaint history spanning 1990 to 2011. This later dataset charts a dramatic reliability arc, registering a high of 487 complaints for the 2005 model year and bottoming at just 9 complaints for the 2011 model year. Falling outside this specific 1990–2011 analytical window, the 1979 example remains unquantified by these particular metrics, its standing defined by its absence from the documented complaint surge that characterizes the model’s later history.
