I just bought a new 2013 T/A Challenger R/T in black. It's an absolutely bad @$$ looking car. The thing I like about it is that it's rare. The one I bought is the first I've ever seen on the road. The other thing I like is that it's not advertised as such. You would have to be a die-hard Mopar fan to figure out the external appearance package is the T/A. I found this one on a lot around here and pounced as I've been looking since January.
That said the car is amazing. The 5.7l Hemi has as much HP as the old 400 4-barrel (375). The power is a little like God, you know it's there and it makes you feel comfortable, it's quiet but it's there when you need it. I wound up getting the two tone leather interior, red and black and it's go the power sun/moon roof.
I'm ridiculously happy with the car, I've been waiting for something like this for 30 years. As for handling and such? Exquisite.
As far as Ford, yeah let's supercharge a 6.4l Hemi and see what kind of HP you get. Bet's it's over 590.
As far the Camaro? The place I bought from has had three traded in for Challengers.
