Nissan products don't have the refinement of Lincoln products and as long as Nissan keeps spending all their R & D dollars on cutting-edge styling, their cars never will be refined.
The salesman at the dealer thinks the MKS rides better than the Town Car. This may be an attempt to keep me interested in the MKS, but if true, it's ride should be on par with a MB S-Class or Lexus LS (an outstanding selling point).
For the best ride comfort, I'd stay away from the large wheels and tires with tiny sidewalls.
First thought here is that cutting edge styling costs no more, for the most part, than bland styling. In this market, it does have added value, as people grow tired of the same old stuff. The R&D funds are being spent elsewhere.
As for the ride, my thought is that the best ride is the one you hardly notice. This would not be the one that crashes over road imperfections (my Prius), or the one where you think about how soft and pillowy it is, and realize just how much you're going to have to slow down for that next dip to keep the nose from doing a face plant in the middle of it(Town Car, base model Caprice).
I'm astonished that no one, as yet, has mentioned the Motor Trend review of the MKS. It's fairly laudatory, actually.
What has surprised me here is that no one has mentioned the Audi A6 in the discussion of this car. That would be one car it is fairly similar to, wouldn't it?
