<human>: Can you succinctly summarize the text in 1-3 sentences?

**Backstory**: I bought a car (private seller) in California, I live in Nevada. From my understanding, I had 30 days to register it in NV. A week after I brought the car back I got a notice from my apartment complex stating that if I didn't have a *parking pass* on my car then it would be towed. I got the parking pass, but 3 days later my car was towed. After getting a hold of the towing company, they stated that they towed it because the registration was expired. 

**But if I never would have gotten the warning about the parking pass, then it would not have gotten towed**

Fast forward to yesterday...For whatever reason, my grandfather (in CA) decided to go to the DMV and found out that my car has been registered in someone else's name. Meaning that the towing company put it up for auction and sold it. *From MY understanding* a towing company has to inform you that they will sell your car if it's been there for too long...I never got any notice.

I'm at a lost here Reddit. I have been trying to find paperwork proving that the car was registered, or some sort of proof that they illegally towed my car. Apparently I ran out of time. My mother suggested that I go to the police station and report it as stolen, but I'm unsure as to whether this *actually* counts as stolen.

What can/should I do?
<bot>: My car was possibly illegally towed, and then sold 2 months later, without the towing company informing me that they were going to sell my car
