I got my LeSabre from a great-grandma who had stopped driving in 2012 and had put only 39,000 miles on it. Despite it's "fuddy duddy" image it has been a great car. Its very roomy, actually gets decent gas mileage on the highway (mid-upper 20's?) and makes for a good road tripping car. With the exception of one additional window that had to get fixed, and one that may stop working at some point, it has had no significant issues. Of course as the car aged normal wear and tear started costing me as things started needing to be replaced.
The car has only broke down on me twice. Once because of the cheap plastic elbows. I replaced them with metal once. Second time because of intake manifold gasket, valve cover gasket (front) and tensioner pully. Cheap fixed thought but I love this car because in city I get 28.2 mpg.
I have owned many cars in my life, and this is definately one of the best. With just under 180K on it, I am now having to do the first major repair, an intake manifold gasket. I have read many negative reviews on this model, and would question how much care has been taken of the car. I have done regular oil changes, tuneups, brakes, etc. that any car needs, and this car has never left me stranded. I would buy another buick when I need another car without question. I wish they still made Lesabres.
I replaced a Buick Park Avenue with a Le Sabre Limited two months ago. Only option is 16 inch wheels. It's a couple of years newer design. Not one problem or complaint so far. Yesterday I drove 380 miles roundtrip to see a Spring Training Baseball Game. We were extremely comfortable cruising most of the time at 75 MPH. Only used 3/4 tank of gas (29.5 miles per gallon burning 87 octane gas). Very pleased to say the least!
I got a deal on this car used, one owner, only 30,000 miles; but the deal went sour after repalcing all four window units at about $600 a pop. Now my rear passenger side door will not lock or unlock (except manually) and the window will not operate. I was told it was a module that would cost around $400 to replace. I am not fixing it; I am selling the car. This well maintained car with only 66,000 miles probably has a lot of good wear left, but it is costing me money parked in my driveway most of the time. I am not going to risk spending $1,000 per door. Anyone hears of a class action, I am in!!
