Reminds me of a friend I had in high school in Atlanta. His dad, Jim Southard, ran Atlanta Classic Cars and was very active buying and restoring older cars and then selling them either outright or at auctions. The same model, different color, car that years later would be in Ferris Bueller, a Ferrari 250 GT SWB California Spyder, was sitting in Bob's garage (they had ~16 car garage on the back of their house), his parents were out of town and left him in charge of the household (he had 4 younger siblings), so of course we took it out for a drive.
Bob was very careful with it, but that V12 singing at high rpms was incredible music to this 17 year old. We only drove it for maybe 15 miles or less but that of course included a trip to the school parking lot so he could show it off to whoever was around (sports practice, and Bob knew cheerleader tryouts were that afternoon

). Bob had a '68 Shelby GT500KR that he was fixing up (he bought it for ~$2800 as NOBODY wanted an old muscle car that needed "leaded gas" and got 10mpg in 1975), and I don't think the Ferrari was that much faster than the Shelby, but it sure sounded a million times better.
His dad sold it for $16k (which was a LOT in 1976, about what the then new Porsche 911 turbo cost), but take a look at what the exact same car sold for in 2009:
