This is our "trip car", purchased new in 2001, it's a 2001 Merc Grand Marquis. 2.76 rear gears makes her a long legged mile eater, I have added a CVPI dual and Addcos F&R and Bilsteins ..... and air lifts for those times when she's carrying us across country with a full trunk. She lives under her cover, has near 68 K now in 2013 .... averaged 26-27 mpg in 21 days and 7,955 miles in our 2006 trip doing Rt 66 and Yosemite and etc ....
