Beyond comparing just the SRT and R/T to the mustang GT, think about this:

26,080 - Mustang GT base price
26,360 - Charger SXT base price

If they keep the bells and whistles of the SXT model charger on the challenger the V6 could well be more than a mustang gt. If they make it more like the SE it could go as low as 23k. The R/T and SRT at least give you more HP for the money. But paying MORE money for less power? Granted I'm getting it regardless, but they really need to keep the price of the V6 down.
