"I think there are a lot of people in the world — particularly in the U.S. — that are attached to having a car," said Puente. "And it's going to be hard to rip them away from it."
Nah, I'm just attached to having money.
It sounds like you don't even get the really high end cars either. Mercedes E-Class? That's only a $50-60k vehicle. Payments would be ~$1k/month with a traditional loan and then you own the car outright after five years. Granted this service includes maintenance and repairs, but that pales in comparison to the ~$7-8k/year you'd be saving.
Save even more by buying it slightly used. That's what I did with our Porsche. $84k new, bought used for $52k. Payments are $1k/month for four years. Everywhere I go people think it's really special, not realizing it cost us the same as their neighbor's boring GMC Yukon.
