Duncan’s Auctions has nearly 75 years of classic car experience. Joe Duncan, founder of Duncan’s Cadillacs in Los Angeles taught founder, Rick Duncan, everything he knew about the auction business. Rick grew up in the classic car auction business, helping his father in his 3 Florida auto auctions.

Rick has been in the classic car business since the passing of his father in 1981. “If you are searching for a comfortable and honest venue to buy or sell a classic car, we invite you to participate in a Duncan’s Auction,” Rick said. “There are many great classic car auctions nationwide and our goal is to bring the same to new venues.”
