Turo can be cheaper than regular car rentals - basically AirBnB style car rentals. Do your own verification of course, but our car insurance with Progressive covers the same as if it was a more traditional car rental service - I called and asked this specific question before I was willing to try.
I'm always wanting to rent a car in Chicago specifically, usually at Midway and the prices have sometimes been so high I actually ride the train to my normal final destination in Kalamazoo, where I wind up renting a car unless it is a super short trip where I'm not expecting to do much in the way of transportation once I get there. This year, close to Thanksgiving - just woof on what I've been seeing on "normal" rentals, so we have a reservation with Turo for our upcoming trip. Since it is just like a friend picking you up, it theoretically can be even more convenient than the usual rental cars. In Chicago anyway, the "just leave the car in the hourly garage" we go to do last time was amazingly convenient - no checking out, dragging everything to the bus, riding the bus. Get out of car, snap 4 or 5 pictures and leave.
