Dealer didnt disclose demo car accident

I was hoping to get some advice. I leased a 5 series demo back in 2019. The car had 4,000 miles, and the dealer stated it was a service demo. I was debating to buyout my lease, and a carfax report shows the car was in a rear end accident a month before I purchased it. I am also shown as being the second owner on the car, even though my understanding is that demo cars arent suppose to show two prior owners. I am a bit ticked off about this, because I obviously would have negotiated a lower price on the car if I knew it was involved in an accident. Also if i buy out the lease, the accident on the carfax report hurts the overall value. Are bmw dealers allowed to lease demo cars without disclosing prior accidents? Should i reach out to BMW to discuss this issue? Any chance they will waive my mileage overage or inspection costs on any damage? Or am I out of luck?
