The Drive has an interview with former jewelry store robber and driver Larry Lawton (who seems to have a YouTube channel). Lawton explains how to choose an appropriate getaway car.
All were simply rented from a company like Hertz under somebody else's name with Lawton listed as the co-driver. They were picked up as normal and simply returned when the job was done. Lawton and his accomplices would pay for the car, case the store they planned to rob, and then use it in the actual robbery.
