Auto Subscription Services. Apparently some auto companies are already doing this and M-B probably will very soon. Instead of purchasing or leasing a vehicle, you "subscribe" to it. Some information on internet about it and Edmund's has a fairly clear one.https://www.edmunds.com/car-leasing/...-services.html
All maintenance, insurance, etc. is included in monthly charge. You can change vehicles often from the models provided. Think most of them will be previously owned. To me it sounds similar to renting a car for longer period of time.
Supposedly it was created as a way to appeal to millennials.

 

I heard that Porsche Atlanta is doing for 2000$ per month and you can switch to any car you like (based on availability).
I can have Porsche 911 the whole month or switch to cayenne for a family trip.

 

If the price is right I can see this being successful. But I also like owning my vehicle and modifying it so we'll see what happens.

 

Will be interesting to see if this takes off. Personally, this doesn't appeal to me but I could see how others would be interested. There are too many slobs out there - I don't want to share cars with other folks.
