The full-size car segment is fairly staid, with no new model introductions, according to J.D. Power segmentation. Although retained value improved year-over-year in December, the segment still lags all others. One driver of the increase in retained value is that incentives were higher in December 2005 than December 2004. Higher gas prices may also make these vehicles more appealing to consumers needing more space but also looking for fuel economy.
