A one-owner 1971 Ferrari 365 GTB/4 heading for RM Auctions' Amelia Island sale in March may be the world's first-ever "condo find."

Like a barn find, its owner left it neglected – in storage – for decades, to lay buried under years of dust; like a barn find, it's full of time-capsule-worthy little relics—the "Disco Rock" eight-track still in its player, for example.

Unlike a barn find, this V12 Ferrari was found not in a shed on its owner's rural country estate, but in a condominium parking garage in downtown Toronto. Wait, what?

The seller and original owner, Toronto's Patrick Sinn, picked up the Daytona in '71 for $18,000 after he saw it at that year's Geneva auto show. He spent that summer touring Europe with it, then accompanied it back to Canada (via New York) on the Queen Elizabeth II.

In 1989, his father's sudden passing forced Sinn to put the Ferrari up on blocks and move to Hong Kong for what he thought would be a short time—but turned into six years. The car sat in his condo parking spot since then, until he decided this November to let another enthusiast restore and enjoy it.

The Daytona has been brought back to running condition, but RM suggests its buyer give it a more thorough overhaul before extensive use. Pre-sale auction estimates put the value of the car at about $600,000, but we'll find out for sure in March at the Canadian firm's Amelia Island sale in Florida.
