1999 Mercury Grand Marquis GS 4dr Sedan

Review

i have had my mercury for 2 yrs. I've had the fuel pump go out on it twice. For those of you who have to change the pump, change your fuel pressure regulator that caused the pump to over work. it a great highway car. but, the mpg is poor. I'm getting a Buick. i love mercurys. they have poor mpg. the 3.8 n the buick has a intake manifold problem. i've changed it in my merc,

Favorite Features

power, handling, stable as a rock.

Suggested Improvements

get a buick.
