When I was shopping, I drove both the Charger R/T and the Challenger SRT-8. I went with the Charger because I felt a better throttle response, the 4 doors for the family, and it came with the options that I wanted with out having to order and wait for a challenger to be built.
The car is very comfortable and roomy. So I got the best of both worlds. Family sedan and horsepower to play when I am alone.
The only thing that I hate about my car is the weight with all the options. My car weighs in at a tubby 5300 lbs. WOW!! So even after I spend the money for power upgrades (one of them to be a supercharger) and get the charger up to around 440 HP without a tranny swap, I still won't be able to hang with vettes and stangs that have half the work, half the money, and 1000 lbs or more lighter. But like I said, I will have the best of both worlds, luxary with HP. I am not a racer anyway. I just like to go fast every once in awhile and hear the engine pounding out the tones that I love to hear.
