Truth in Advertising (not)

Compared with my 1997 grand marquis which was quite economical (25-26 mpg hwy & 18-19 local) My 2003 gets 22.5 hwy and 15 mpg around town. Very disapointed in the 2003 as I was expecting similar economy on the 2003 since the window sticker claims 19-25 mpg just as it did on the 1997.I blame it on the unnecessary increase in horsepower.Truth in advertising!!???

Hard to be Objective

It's hard to be objective when the car is perfect. We've had it for a year and we've never had a single problem with the vehicle. We purchased it from my Grandmother and she never had a single issue either. We towed a 3K lb. trailer from AL to UT and it handled the trip with ease. No problems whatsoever. Gas mileage for the trip was around 15 mpg. I was amazed. The car rides smooth and is very quiet. Three car seats fit in the back with plenty of room and we can seat three adults up front. We have enjoyed owning such a reliable vehicle. We put about 15K miles/year on the vehicle. We would recommend it to everyone.

Honest real world opinion

My driving and ownership experience. Hmm. Well all said and done, second too none. The MGM is by far the best car I have ever owned, inside and out. I've given this car the highest ratings all around including fuel economy. I find though my research most larger cars as well as mini-vans or other family sized vehicles average around 20-25 mpg. I average about 25 mpg (26.7) to be precise with my Grand Marquis. Now factor the size and weight and power of the car and compare that on a scale to ANY small car or large car. You will find the MGM is the green or most fuel efficient car on the road. Outside of fuel economy, I rate the reliability five stars. MGM has a proven record and still holds it.

underappreciated car

This is my first "panther platform" car. I'm 60 and have had hundreds of car and pickups. This is by far the most bang for the buck. I switched to Mobile 1 synthetic oil in 5-30w, added dual exhausts with an "X" pipe in the stock placement. Would you believe 28 mpg with the A/C on. I would imagine I can hit 30+ on the highway on cruise at 70mph. A simply great car, it rivals my Mercedes in comfort and handling....and replacement parts are dirt cheap. Even the Russians use this vehicle as their police cars. Rear wheel drive, proven drive train, and for 2003 you get a lot of improvements...Simple, strong, reliable.
