Buick Lucerne
It is an awesome vehicle, the finest I've ever owned due to the smoothest ride, low maintenance, with over 200,000 miles on it, still not using much oil. And I've owned various cars, 4 pre-owned Cadillacs, a 2952 Buick, several Oldsmobiles and a VW Rabbit. Wish they still made Lucernes but I suspect it's replacement is just as good
