Mercury Grand Marquis Reliability and Durability: Pros

Checked and they have a very good reliabity and durability. That makes a lot of comfort

I put over 90000 miles on mine, with zero issues.

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.

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