Ford's 4.6 liter V8 and 4r70W transmission are bulletproof and reliable. The body-on-frame design is built to withstand taxi and police use. Plus, the whole car is designed and marketed to previous generations that value durability, quality and reliability -- rather than younger generations that value Bluetooth and touchscreens. see full Mercury Grand Marquis review

A daughter had 9 year older Grand Marquis with no problems. Aged Panther platform has all the bugs worked out. see full Mercury Grand Marquis review
