The “suitcase” is in reference to the mufflers which even though they are “dual” in nature are a one piece unit which many feel have the look of a “suitcase”. I thought they were still using this arrangement on the new SRT’s, but could be wrong. I know the exhaust is different for the RT vs the SRT due to the MDS and likewise there is a difference between the auto and 6-speed Challengers.
In addition they have “beefed-up” the 2009-and newer rear-end pieces over the 2008 including offering a limited slip differential.
But, overall not much in the way of really big changes from the 2008 models. Different colors being offered but not a lot of new or different options, mostly add-ons. Looks as if 2011 may bring some changes, we’ll have to wait and see.
The 2008 models were numbered, which is nice…will it make a difference in future value….only time will tell……
