Putting a hole in your thief's head would probably cure your PTTS. But alas, two wrongs don't make a right, and your thief is protected under the law and has more rights than you.
An alarm system that has GPS and real time alerting to your phone is good. Get one that has ignition immobilizer, proximity, shock/tilt sensor, and siren add-ons. Have a reputable shop install it. Have the dealership install all the latest security updates, especially the one that locks the RF-Hub. Neutral pull cover is a must. Good that you have it. I recommend using cover bolts with a rare/unique head for added security for the tenacious car thief pond scum. Parking it in a locked garage is great. Store your keys in a quality Faraday pouch or box (read reviews!). Don't park in a ghetto. Don't live in a ghetto. Same with low income areas. If you live in a shitty place like Detroit or Chicago, consider moving someplace that doesn't look like a third world country and sound like Afghanistan at night. Seems like a lot of Challenger thefts happen on the east coast and in Texas. Theft can happen anywhere though. The goal is to minimize the likelihood of becoming a victim through layered security and by avoiding risky situations.
You've done a lot of things right. The car means a lot to you. Having something meaningful stolen from you is very violating. But in time your PTTS will pass. You should consider seeing a therapist about it. I'm serious. It might help you get past this. Nothing wrong with going to one. Remember, your car is meant to be enjoyed and driven!
