First off, congrats on your new car!
Second, not to be Debbie downer but if you are new to HC's the very first thing you need to do (assuming your picture is indicative of where you live) either get a garage (again assuming your complex has that option) or invest in a hidden GPS tracker/security system. The Dodge security system is a joke and HC's are some of the most targeted and stolen cars based off % of built cars. Seems like every couple of weeks someone post about theirs being stolen. Again, not trying to be downer but wanting to help as best as possible preventing you from being the next person to have to post that. I wouldn't let it deter your enjoyment of the car as that is what insurance is also for but also take some extra steps to help if you are parking it outside.
3rd, as stated above, if staying stock a warranty is not a bad idea. With 20K miles on it most of the bugs should be worked out and assuming proper maintenance you should be OK but the added piece of mind can be nice for some. Just make sure you get a reputable one with good reviews as some aren't worth the paper the documents are printed on.
Lastly, congrats again on your new ride! Enjoy it as much as possible.
