Made it to bed around 2am last night. Was well on my way to sleep when a car starting outside woke me up. I went to the window to find a car parked next to my car, away from any houses. Someone got in the passenger seat of the running car, and then it pulled away, in reverse.

I think my car was just cased. I went outside to check and everything is intact. I think my stealth install just saved me some money.
