Great car you can count on
Oil pan gasket at 7000km.
Trim on driver's door twice around 20,000km.
Air ride line somehow broke in the winter at 60,000km.
All repairs done under warranty.
I bought this car brand new after owning 6 or so GMs based on this architecture; I figured I was safe with buying the Lucerne. I ordered this car with cloth and a bench seat, plus all the comfort features I wanted.
Noise: This car is sarcophagus quiet; you shut the door and it's like you're in a tomb. It is incomparable to anything I have been in under 100,000 (Lexus, Infiniti, BMW, Merc, Lincoln). When you do some digging online, you can find that Buick spent a lot of time ensuring this car would take on a lot of tier 1 luxury cars in terms of interior sound.
Ride quality: I give 7/10, now I have been in smoother cars. The only things that come to mind are the Roadmaster and the Town Car. I owned a Park Avenue Ultra before this, and I do find the Lucerne to ride slightly nicer and it's a fair bit quieter. For uni-body cars for the time being, I think this is as good as it gets.
Engine: Although the 3900 does a decent job at getting you up to speed and giving you passing power, it's not the best. If I would have spent more time test driving, I would have bought it with the V8. The 3900 isn't a bad engine, I will pull low 30s for MPG on the highway, but I would have preferred the 3800 for peace of mind. I would have liked to see this car with a 3800 or a 3800 S/C for 2011.
Overall this is a very nice safe highway cruiser, and I'm sad to see this platform go. IMO I think this platform from GM could go toe to toe with any other manufacturers in terms of reliability. After driving quite a few new cars, there is nothing that can compare in terms of smooth ride and cab quietness.
Would you buy another car from this manufacturer? Yes
