Cars can pass through many of the medina's narrow alleys, but not all, and unless you know the lay of the land you risk getting suddenly stuck and being hard-pressed to perform a U-turn.
Parking in Marrakesh is relatively easy; barring the red-and-white-striped gutters, you may park almost anywhere. Throughout the city, guardians (who usually wear blue overalls and a brass badge) watch cars in parking lots for a few hours for 5 DH, and 10 DH overnight.
By far, the best local car-rental agency we found was Rent Med; run by a super-helpful staff, this company gives very competitive rates on a range of small cars and larger all-terrain vehicles, all in good condition. They can also provide chauffeurs if you don't feel like driving. As a general rule, cars cost between 300 DH and 400 DH per day, while four-wheel drives cost 900 DH to 1,000 DH per day.
