SANTA MONICA, CALIF. — After being knocked out of commission in 1969 by an engine fire and then spending the next 44 years hibernating in Pennsylvania, a graceful 1967 Ferrari 330 GTS will come under the glare of spotlights on Jan. 18 when it is auctioned in Scottsdale, Ariz.

The 330 GTS, one of only 100 roadsters in the series dominated by the 330 GTC — its mechanical twin, but a coupe body — is an example of how mid-’60s Ferraris are receiving new appreciation as prices for the Italian automaker’s vintage cars rise, David Brynan, a Gooding & Company auction specialist, said. Gooding will offer the “Spider,” or convertible, among approximately 120 cars at its two-day auction.

The Ferraris that draw multimillion-dollar bids at auction are, for the most part, immaculately restored examples; a significant racing history or association will also raise the sale price. This car has neither, but instead is valued as an original car with a clear ownership history.

Found in November with a coating of grime, spots of surface rust and a blackened and cracked windshield, the Celeste Blue GTS is all the more desirable as a nearly untouched example of the model, which helps Ferrari collectors and restorers to establish a baseline for the 330 series, Mr. Brynan said. The car, chassis number 9343, was consigned by its present owner, who ferreted out its whereabouts in a two-bay carport in suburban Philadelphia and made the acquisition.
