I've never owned a new car, and I doubt I ever will as they don't build the Vic and Grand Marquis anymore.
My very first brand new car was my first 2008 black Grand Marquis LS. I have 233K miles on it now and it's chugging right along. The local dealership where I bought it says that customers are really disappointed with Ford's decision to discontinue the Mercury line. The Grand Marquis filled in a significant niche between the Ford Crown Victoria and Lincoln Town Car. I'm glad I made sure to get another one before I retired. My twin black Grand Marquiss are probably the best known cars in town.
