I bought this car in February of 09 with 83K for approx. $2,900. An older gentlemen owned it and it was garaged and well maintained. Prior to this I owned an 04 Ford Expedition EB edition that was costing $600.00/month. I got rid of the gas guzzling money pit and since I have owned the Lesabre, I have spent less than $800 in total in almost 4 years.
I'm amazed that when I drive 235 miles to visit my mother, it gets around 27-28 mpg and about 21-22 around town, but best of all, no car payments, fits 3 baby seats and keeps plenty of money in my pocket. At 135K, it has some quirks, but nothing major.
Quiet engine, inexpensive to maintain, good mpg for a full size car, handles well in poor weather, plenty of cabin/trunk space & comfortable.
The improvements I would have suggested were made in later years such as 4 wheel disc brakes.
