Here’s a trivia challenge for movie buffs.

Describe the make and model of the car that paranormal investigators Ed and Lorraine Warren drive in the upcoming supernatural thriller “The Conjuring.”

Unless you are psychic, it’s an impossible challenge because the movie doesn’t debut until July 19. But if you go see the flick, you can tell friends that the vehicle is a locally-purchased 1968 AMC Ambassador SST with a 290-horsepower V-8 engine, automatic transmission, air conditioning and 103,000 original miles.

The movie producers bought the Ambassador from Berkeley County resident Mike Smith, who deals in classic and antique cars.

“It’s going to be the main characters’ car,” he said. A glimpse of the car is provided in a movie trailer posted online.

Smith said he has provided other cars for movie makers too.

“The Conjuring,” said to be based on a true story, tells the tale of the Warrens, played by Patrick Wilson and Vera Farmiga, who investigate a rural farmhouse haunting in the early 1970s.

The movie is about supernatural occurrences at the home of the Perron family of Harrisville, R.I. The Warrens find themselves caught in the most terrifying case of their lives, says Warner Brothers.

The picture was filmed in the Wilmington, N.C., area at locations including the local campus of the University of North Carolina.

Smith is president of the Lowcountry Regional Chapter of the Chevelles and El Caminos Car Club of South Carolina.

He said the movie producers bought the car from him in January of 2012. He said it was a rare find in Pennsylvania because of the low mileage and its condition.

Smith, who is in his 70s, said he also sold a Volkswagen dune buggy for use in the Paul Newman movie “Sometimes A Great Notion.” And there was a 1932 blue roadster he dealt to the movies for “The Shaggy Dog.” A number of B-movies also have used vehicles from him, he said.

Smith, who lives near U.S. Highway 17-A and Cypress Gardens Road, said the producers of “The Conjuring” contacted him about the Ambassador SST.

Movie officials contacted through the Wilmington Film Commission said the “picture car” staff was not available for comment.
