1994 Buick LeSabre Reviews

I really don't care about any of the features. I was just in an accident today in my '94 lesabre and came away with barely a dent, the other car was totalled, and everyone came out just fine. I love my car, even though it may be dinosaur like at some points I really don't give a jizz because it saved mine and two other lives today. Dinosaur lover
As long as you take care of this vehicle it is a nice vehicle to own. The only down fall is the quick rust on the bottom of car and high cost of maintenance.
Very nice car but the bad mileage is TOURIBLE! I bought it from 5 days ago. very helpful and comfortable car like a boat! But I didn't know what the 10 mpg caused by? It chocked me!
