The attack is considered the deadliest mass shooting in recent United States history.
"The Hyundai that was sought in connection with the LV (Las Vegas) shooting was located during a search warrant executed at (Stephen) Paddock's house in Reno", Las Vegas Metropolitan Police Department (LVMPD) tweeted on its official page.
Investigators have yet to determine the motive for the rampage Paddock carried out from the 32nd floor of the Mandalay Bay Resort and Casino, killing 58 people and injuring nearly 500.
Police were searching for two vehicles the night of the shooting, but one of the cars was found that night.
So far, investigators have found no evidence supporting a claim by ISIS that Paddock had converted to Islam and carried out the attack on the terror group's behalf, according to the information provided by the source.
Paddock reserved rooms at the Ogden, a luxury condo tower in Las Vegas, for September 17-28.
Investigators also found a note containing numbers inside the hotel suite, but police say it was not a suicide note or manifesto.
