Purchased in 03 with 52K, now has 265,000 miles. Engine has never had the valve covers removed. I have no plans of getting rid of her. These cars are cheap to maintain with plenty of original parts on ebay etc.. Obviously I have taken care of it.
This is my 4th or 5th Town Car, and my second one in this body style/engine configuration. These are solid, dependable, and well appointed vehicles. What little gas money you might save in a lesser car is more than well compensated by the lower long term ownership and insurance costs. They have everything, and they don't break a lot...and no payments! This car provides a comfortable and quiet ride, (reasonable) power(it's NOT an LT1), and reasonable gas mileage. The pollution control system is not so invasive that you cannot touch the car without having it become a problem, and the traditional styling and build are a plus for maintenance and/or modification.
My grandparents bought this car brand new as soon as it showed up at the dealer. I think the original list price was $47,000. My grandpa has since died, and in 2005, my grandma didn't feel safe driving anymore at the age of 88. She loved that car and wanted to keep it in the family, so she gave it to me, knowing I'd take the absolute best care of it. It had 31000 miles when she gave it to me. This is the most luxurious car Ford ever built. Has been very reliable, but when things have to be replaced, it's very costly for parts. It now has 102,000 miles and still drives like a dream. I never cared for the newer body style that started in '98 or '99. I'm very grateful to own such a classic car.
Bought the car with only 24K on it. Didn't need front brakes until 85K, rear brakes at 130K (lots of highway miles in my business). This was the best designed car for comfort and ease of driving that I have ever owned. Everything can be adjusted to wherever you want it for all circumstances by whomever was driving. Being a somewhat small woman, I particularly appreciated being able to position the driver's seat so I had ultimate visibility yet all operational controls were still readily at hand, even the cup holders and ashtray. Other than routine maintenance, repairs weren't needed until 135K. Last 15K saw rear air springs and compressor, fuel filter, external brake lines,etc. Great car!
