Gotta say stowing away a 1974 Maverick 4 door like it was a Faberge Egg is impressive, as well as confusing
I mean, I'm just trying to imagine some 1974 guy in a leisure suit sealing a new 4 door Maverick in a glass climate controlled vault, convinced that it would someday be a priceless collector's item. I'm assuming drugs were involved
The opposite example is the 2005-06 Ford GT, where 95% of them were immediately stowed away and the only mileage they have is going across auction stages. I would freaking love to see one with 100k miles, that would be the REAL collector's item
If that Maverick is the Yin, here is its Yang- a real deal, vintage race provenance, street driven 1965 427 side oiler SC Cobra, complete with dents and bondo. Saw it a few years ago in Burbank, maybe the coolest street car I've ever seen 
I was at a car auction a few years ago that had a 1969 last year Corvair and 1969 1st year Vega, both with <10 miles. Owned by a Chevy dealer who socked em away, which I guess made some sense. They each sold for <$10k, which after inflation meant they both still depreciated.
On the other hand, these two unassembled still-in-crate 1986 Honda Z50 Christmas Edition minibikes sold at auction earlier this year for $51,500. I think they were about $750 new
to be fair these weren't your run of the mill Honda Z50s (which btw was my first motorized vehicle). These were holiday bonuses from Honda to their top US dealers, with special chrome frames, and no title so they were not for sale to general public.
