its not that much more money when you compare a fully loaded 4.4 to a 4.8. Most of the extra money for the 4.8 is because all those options are standard and are not on the 4.4. If its your only car i would definately go with the 4.8 main reason for me is the brakes. Alot better than my 4.4 I went with the 4.4 cecause i already have a few sports cars and didnt really think i needed the 4.8 but next time around i may go for it.
