newer challengers

Thinking of buying a newer used challenger w/manual trans. This would be mostly a daily driver. Are there certain years that are better than others? Used RTs are a good price point but I think a used low mile SRT might be the way to go. Thinking of a 2009 or 2010 but could get newer. Will probably end up keeping forever and just rebuilding later. I can afford a new one but would prefer one that has depreciated a bit. Thanks for any sage advice.
