The vehicle, whose new owner was not revealed, was used during the final three seasons of the award-winning HBO series.
"The Cadillac Escalade represented Tony's personal car and primary means of transportation, frequently used to show him going to and from his own driveway, meetings with members of the New York families, and the notorious landmarks of the Sopranos' fictional universe like the Bada Bing strip club and Satriale's Pork Store," a news release said. "It was also utilized in action sequences including the infamous chase from Season 5 in which Tony, angrily trying to collect a debt, drives Phil Leotardo off the road and into a parked car."
Gandolfini, who died in 2013 at the age of 51, prominently signed the interior of the Escalade twice in black felt-tip pen -- once inside the driver's-side sun visor, "Thanks for the truck, James Gandolfini," and also on the panel above the glovebox, "James Gandolfini."
"For fans of the show -- it's an instantly recognizable prop from one of the most acclaimed television series ever produced," Robert Livingston, executive vice president at R.R. Auction, said in a statement. "Once we had realized we had broken the previous sales record price for a Sopranos used vehicle, we were thrilled with the results of the auction."
A 1999 Chevrolet Suburban from The Sopranos Seasons 1-4 sold for $110,000, in 2013.
