2006 Mercury Grand Marquis GS 4dr Sedan (4.6L 8cyl 4A)
We have 109k on this thing and the only thing that's happened is 2 overheats. The ride is smooth, the engine sounds awesome, fuel mileage is nothing to write home about, but what can you expect from a V8? It's very cheap to maintain. We drive anywhere from around town to across states, and it's fun and easy to drive either.
2006 Mercury Grand Marquis LS Ultimate 4dr Sedan (4.6L 8cyl 4A)
Buy it. Grab one now! Spacious, GREAT smooth ride, ok performance, super inexpensive to buy, maintain, repair and insure. It's no sports car, it's certainly no gas miser Prius (12 dense traffic, 16 mix, 23 highway @ 80mph), but if you want a comfortable, roomy, low cost per mile ride this is it.
The interior materials are not high quality but are serviceable. The trunk is good old American sedan huge and the car seats five comfortably, six in a pinch. The rear air suspension does a great job of keeping the car level when loaded. The handling is not as bad as some write ups would have you believe. It's open differential RWD without stability control. If you don't have a reasonable understanding of physics, go find a modern nanny-mobile to do the driving for you.
You can drive over pot holes without worrying about blowing a tire or knocking the front end out of line. It's much more forgiving than a modern FWD with weenie low profile tires. Personally, I got tired of replacing tires and wheels during winter driving. 2006 and newer models share a solid 4 speed transmission with the F150 pickup truck. This is a solid vehicle.
2006 Mercury Grand Marquis GS Convenience 4dr Sedan (4.6L 8cyl 4A)
purchased the car in 2007 with 10K miles on it. after 2 years, the "blend" apparatus required replacement. ( this is the little door that opens and closes to give you cool or warm air.) that was a 1K repair and after 2 attempts, have still not succeeded in putting the dash back together correctly. today I learned that one of fords most reliable models requires a new intake manifold. this vehicle has 92K miles on it. have read many forums about this problem however this was supposed to have been corrected in 2005. NOT!! so if you're planning on purchasing a ford or mercury with a 4.6L this will cost you around 1200. will be going back to Honda later this year......
