I previously owned an 06 SLT with the 4.7. I went and checked out the 08s and new that I had to have one. Next day traded in the 06 for the new one. The new SLT with the Hemi is freakin sweet. When you put the hammer down you know that there is enough power for anything and everything that you could ever need. There is plenty of room and the extra options that you can get make it amazing.
The Hemi is awesome, sun roof, MyGig, back up cam, and the Alpine speaker system sounds so crisp and clean.
The only improvement I would recomend is for the release of a lift kit so that we could fit some sweet rims and off road tires.
