I found my on Craig's list. They are definitely around just need to look. I got a 2007 RT with with 48k for about $14k. One owner and no accidents. Recent trade in. Look at Dodge dealerships. Most Mopar owners are pretty loyal so if they trade them in, that's where they'll be.
Cars.com is a good place. They list new and used plus have lots of research information on options, specs, etc. I've recently seen new 2013 R/Ts there for under 28K.
From my research there I found that one of my local dealerships had dozens of 2013's like I wanted and went there and made a great deal.
