The V-8 is thirsty for city driving. The extra power would be nice for highway & mountain driving, though. see full Mercury Grand Marquis review

Other luxury cars/SUVs require premium gas. Diesel could be same or even cheaper than regular gas and with immense torque and a somewhat light foot I get almost 25Mpg see full Mercedes-Benz M-Class review

Have a V8, so I should have expected, but mpg is averaging about 16 around town. With the current gas prices, I dread going to the pump. $90 to fill up the huge tank. see full Mercedes-Benz M-Class review
