If you live where it snows each winter, I highly recommend storage to keep the car in good shape for years to come.
Google image 1988 Lincoln Town Car Signature Series. It's the shiny chrome surfaces along the bottom of the sides of the car.
This is the original reviewer. I've since purchased a mint '89 Towncar Signature. I had originally thought I would sell my Grand Marquis. It is going to need some attention. But, as previously stated, I'm going to have the repairs done and continue to drive this car until it won't move anymore. At 206k miles, it burns no oil, rides just as quiet, handles just as well, and looks just as good as the day that I bought it.
How many miles on the Town Car? Does it ride more comfortably than the Grand Marquis? My grandparents bought an '89 Town Car Signature Series back in 1993. I went with them to pick it up and I have many fond memories of that car. I was about 9 then, but always loved the big Detroit iron even at that young age. They traded it for another Town Car in 2000, but it was not nearly as nice. Now they drive Honda mini-vans (what a disappointing change), although they do seem to like them.
The '89 Town Car has 82k original miles. The previous owner put on brand new tires, battery, brakes, and EGR valve. The Town Car seems like it's a heavier car. I believe it is by about 400lbs.
As for longevity, you cannot beat these older Panther platform Ford products. The overdrive transmissions seem to be the only real mechanical weak spots. But, once they're rebuilt, they drive as good as new.
Electrical goodies seem to give out over time. Automatic antenna, door locks, window motors. All this stuff can be fixed if you're patient. Still a ton cheaper than buying a new car. And, nothing new rides as good or is anywhere near as comfortable.
