Wikipedia defines the sharing economy as peer-to-peer-based sharing of access to goods and services (coordinated through community-based online services). The internet (particularly mobile access) opened up an entire new ability for people to utilize goods/services that would otherwise go unused -- you can use airbnb to rent a room or house that would otherwise be unoccupied, turo and getaround will let you rent other peoples cars (like this 2016 Corvette for $108 a day), spinlister will let you rent a bike from a neighbor, dogvacay is a good place to find a person willing to watch your dog while you are on vacation, taskrabbit or zaarly are place where you can get all kinds of stuff done for cheap (or get murdered/search for victims), lyft uber
But, can you find a turbocharged depreciated 90s supercar to drive on the weekend in any of these services? Maybe...probably not. Would you want to?
Most of the car related services are geared towards inexpensive daily rentals, but I've envisioned a sharing service like the Classic Car Club of Manhattan, but without the pomp and country club level entry fee. $5k-$10k cars that are cool (you've seen 'em here on these pages) that would be loaned out for a week at a time for a reasonable fee -- or perhaps your donation of your own junker from the 90s. Manual gearboxes would be preferred, but a few old crummy autos would be tossed into the mix....but you see where I'm going with this.
Is this a terrible idea? Or what?
