Much better than the previous design, a pleasure to drive. 30 mpg is real. Problems are the center console and early strut problems. The dash rattles like the older la sabres,but all in all at 40,000 miles its been a great car.
My odometer is sitting at 210,000. This car was well maintained. The only, and I mean only problem with this car is the power window motors. The two rear ones are burned up. Locked them in the up position. Other than that, nothing has been replaced, nothing at all. Just replaced the battery for the first time at 205k (as far as I know). That's it, most reliable car and engine I've ever known.
I bought my Buick new in 2000, it has been great for long trips as well as city driving. Having owned it now for 9 years the only problem I've encountered is the power window regulators which make the windows go up and down. I had to replace all 4 of them. They run about $400.00 installed. Thank God I sell cars for a living so I got a discount on labor and parts. Other than that one problem the car has been great!
I bought it with 40,000 miles, the transmission blow off after one month, it was replaced by the dealer and I just paid $300.00. After that, the heater was fixed, it was blowing cool air by the driver vent, it was fixed @ $700.00, the driver bearing has been replaced and after that, no problem in 3 years. I'm using synthetic oil and maintenance by the book, I drive 104 miles a day because of work. The cassette player never works
