Over the years the demand of the big luxury sedans is declining. The demands for the big luxury sedans have been halved. The sedan segment used to have 15 models, but with the passage of time and changing demand the models have been reduced to seven. The market share that was once above 5% had been reduced to 2.3% in the first three months of the current year. The big sedan luxury segment is now decaying, as the segment in only one-third of the minivan market (Polk Reports, 2012).
