General Comments:
I bought this car new, with the top line option package, which included nearly everything but the adaptive speed control. Overall the car drives fairly well, it is relatively comfortable. I would not rank the ride as great, nor is it a quiet car.
But it is troublesome. It's been back for a number of problems. Ford seems to have an epidemic of PTU problems. Google returns thousands of hits with people recounting the problems with that part. The PTU, Power Transfer Unit, attaches to the transaxle on the right side of the car in-line with the right front wheel's axle. The job of the PTU is to send engine torque to the rear axle via the connected drive shaft. The failure mode of the PTU is that the oil sludges, turns to jelly and gets thrown out of the housing by gear motion. Unlubricated, the gears and bearings fail. If you catch the problem early, multiple gear oil changes to flush out the old lube can save the unit from premature failure, but you have to catch the problem early. The PTU holds only a few ounces of gear oil and is located between the engine and the catalytic converter. It doesn't take much or a long time for the oil to being breaking down. It's not easy to change, but it is possible for a do-it-yourself person to do. If you have one of these lemons, change the oil annually, at least.
The other problem I'm still trying to resolve. While passing another car, the oil pressure warning suddenly sounded with a message on the instrument cluster. The crankcase is full, so it's not a low oil level situation. Normally when idling, I can see oil flowing from a port inside the valve cover area by removing the oil fill cap. The oil flow is currently very low and without any evidence of pressure. I've also removed the oil pressure sensor and confirmed with a gauge that there's no oil pressure. There's no major external leaks. The dealers want me to bring the car to them before they estimate the repair cost, but there's nothing more to see without them disassembling the engine, which at that point, you're on the hook for whatever they want to charge.
Unlike my Lincoln Town car that I drove for 250,000 miles before trading it and the dealer re-selling it to a limousine company that drove it another 150,000 miles, and my Navigator that I drove nearly 400,000 miles, and my Mark VIII that I still own and drive regularly, this car is unreliable junk.
Would you buy another car from this manufacturer? No

This is what you get in place of a Town Car; It's a shame that they were discontinued.

Our one owner Town Car needed every line replaced under it and needed a new suspension.

Northern climates will do that to any car.

Except the car was located at a mobile home park in Sebring Florida.

Yeah, well mine is 20 years old, 216,000 miles, lived its whole life in Palm Beach county FL. and does not have one spec of rust underneath. Though the rear air suspension I did replace with conventional springs at 175,000 miles. I've worked on many vehicles and have never seen a Florida car with rot on the undercarriage.
Seems kind of strange it could have happened to your Lincoln. Sorry to hear about that.

Cars in many parts of Florida do rust. And not just the coast. It rains often in many areas, even if just for short periods. The recent hurricane will now have many flood damaged vehicles for sale. We also had a Range Rover with a failed suspension. People that tow boats and personal watercraft can also have suspension issues using boat ramps. The intense tropical sun cracks dashes seats and fades paint and interiors. Even with a garage or carport. Adding more tint is common. We have had tops warp on other convertible models across the front to allow rain in.

Aftet living in south FL. for 25 years and working on cars 20 of those years, I have never once seen (on a Florida car) rust on an undercarriage to the point where the brake and fuel lines are leaking. Rot that bad is caused by road salt in a northern climate. We do get massive amounts of rain which will cause body rust way before it would take its toll on a steel chassis with steel lines.

We have 2 Edges, one with 168k, and one with 190k. No issue in this area. The My Touch is another matter. Buy a 2010 and it does not have this.
