What I love the most about this is the fact that it's peer to peer since that comes with a ton of benefits. If you're renting a car from a business, the price is way higher, one, because they have full control over their price, and two because they have a business to run, which raise their cost of running higher. But, getting it from a normal person just like you surely lowers the prices, as it can be seen on the site.
Keep on hunting.
