Legal Question in Real Estate Law in Nevada

This a very interesting dilemma! The first thing that jumped out at me was how could you have received a title to a stolen vehicle? Maybe the private party from whom you bought it took the car and title from a roommate or family member, and passed a good title (albeit with a forged seller's signature). If that is the case, you are what is called in the law a "bona fide purchaser for value." You may have protections as such, and especially after the passage of so much time.

After getting the title in hand, did you not transfer it to your name? I assume, therefore, you never attempted to register the car in Nevada, either.

The next issue that seems a bit odd is that the State of Illinois was able to register the vehicle for you. Did they not require that you surrender your Nevada title to get it re-titled and registered there? If another state accepted the title and transferred it to your name, I would be very surprised if it did not come up on a multi-state database as a stolen vehicle.

Really, this whole scenario sounds quite unique and I would enjoy working on a matter like this. If you seek legal help, you'll have to gather all the documentation relating to the car and try to reconstruct a bit of a timeline of all that you have done since buying it. Avoid appearing to be dodging law enforcement, though, as you surely don't want to be charged with any offenses related to making it hard for them to do their investigations.
