You are talking about Chrysler. There is no such thing as "reliable" information on anything...
Oh, the Hemi/8-Speed is coming
Oh, the Dart SRT is coming
Oh, the Challenger Refresh is coming
Oh, the Redline Charger Package is coming
Oh, the Hellcat is coming
In the 5 years since the Challenger hit the street, Chevy brought the Camaro back, has given it a refresh, and offers up 3 levels of Performance OVER the V8 option.
Chrysler has given us Rocker Panel Stripes....and 3 new shades of Gray.
(most of that was quoted from MCO Carter who said it very well)
