Having owned four LeSabres prior to buying this Lucerne, I can give an accurate evaluation, I think. It is so silent one thinks you should be in a Caddy or Town car.
I guess the quiet ride impresses me the most. Of course the great looks are a plus. It garners stares from those less fortunate.
Add dash lites to daytime running. It's hard to read the instruments. Place the trunk release back on the driver's door as it was on the LeSabre. Put the cruise control button back on the right side of the steering wheel. It's clumsy on the left side. I hate that the battery is under the seat!
