I bought the LeSabre because its fairly comfortable and reliable for a much more affordable price that used foreign-brand models. So far I've been pretty happy. The acceleration is adequate (tho probably not as good as more recent models). The cloth seats are soft but fairly supportive, though the interior design is a bit antiquated. Reliability has been with the only repairs being a throttle ($200) and water pump ($300), and new front brake pads. The styling may not be exciting, but its timeless and classy. (the 2005 model doesn't look too much different). The handling is below-average and parking in urban areas is not fun. Overall not bad for a decade-old Detroit dreadnought.
The seats are very comfortable and I like the design of the power controls on the door.
The transmission could shift a bit smoother and the brakes and handling are not up to modern standards. Buick added 35 hp for 1996 so that was clearly a good change.
