I have had three Mercs two Audis all mid to upper level. I brought a 2008 Lucerne CSX V8 and I am absolutely delighted with it - and would put it up against any car in its class. With what I have on my car - I would have to have paid a fortune in extras on the foreign models. Ultra quiet, fantastic build quality built to incredible tolerances. The Northstar engine is silky smooth. Very respectable mph for a V8 Exquisite lines no matter what angle you look at it. I would recommend anyone looking at a mid or full size saloon to "a least" take a test drive at your local Buick dealership.
The simplicity of the interior design, comfort and quietness of ride.
Five or six speed gearbox - smaller turning circle. Get rid of the Auto Union like Regan did with the Air Traffic Controllers and start all over again - It's a car manufacture - not an old peoples home!
