I got a little bored and with everyone saying how huge the Challenger is I decided to do a side-by-side comparison to see for myself. Below is a general representation of the cars and how they stack up size-wise. I found it interesting so I figure I'd post it here, too.

The Challenger is the biggest in 4 of the 6 comparisons. However, the Camaro looks to be the widest car of them all. Interesting.
