OK, after reading all the posts (some good points made on both sides) I decided to chime in. First thing you should do is actually drive both the Challenger and the Camaro. The Camaro will seem faster because it is a smaller and lighter car, but will only be faster than an R/T if it has a manual. On the subject of comfort, room and ride, the Challenger is a slam dunk. The Camaro will handle better mainly because of less weight and better tires. When it comes to build quality, some things will be obvious now such as comparing the actual materials used in the interiors, some things will be realized later such as rattles, squeaks and the like. If the previous generations of Camaro are any indication, lets hope Chevy builds these new ones better or they will end up traded in like the dime-a-dozen door sagging copies of yesterday. The Challenger is a big car, no other way to say it. It weighs over 2 tons, the more options, the more weight you pile on it. It isn't as nimble as the Camaro, and unless you buy the SRT8, it won't come close to the Camaro's ability in handling and braking. Cool factor and looks? Challenger. Bang for the buck? Camaro. I paid nearly 33K for my R/T with some options, I have 1k in performance mods. I can drive to the track with the A/C on and get 25MPG with the MDS engaged, bolt on some drag radials, turn a 12.9, put my street tires back on, and cruise back home in style and comfort.
Ok, reading this post over, I am a little biased towards the Challenger, but my bank told me to pick out any car I wanted, I bought a Challenger. As to why I bought an R/T over the SRT8, that's another story.
