I purchased my LeSabre Custom exactly a month ago to drive back and forth to college. This is an excellent highway car. The ride on the open road is very smooth and power from the 3.8 liter V-6 comes on strong when you need it to. Carving corners, however, the Buick feels slow and heavy. After driving a Ford Tempo for two years, parking the LeSabre is a bit of a chore. Inside, everything is very accomadating. The seats are large and comfortable, and the radio controls are large and easy enough to use. For a car this size, the itsy-bitsy glove box is a bit of an embarrassment. Despite the weight and size of this car, it has averaged about 27 miles per gallon in mostly highway driving.
My favorite feature of the LeSabre is probably the balance of power and economy. The LeSabre has enough boost to get out of its own way, yet it's relatively easy on the gas.
The LeSabre is a handsome car but still, the styling could probably use more definition. But hey, it is Buick after all. Handling's nothing to brag about and could definitely be improved.
