Yes, but not for the entire time you're in Cape Town. Without your own car, you'll have a hard time getting to a lot of our favorite things to do in Cape Town like the scenic drives, the wine lands, the townships, and some hikes. But you might be better off without a car for the first couple of days in Cape Town, especially if your accommodation doesn't have private, secure parking. Parking can be a pain here and there's a significant risk of someone breaking into your car, so a combo of walking and Uber is a better bet for the city. As for who to rent from, based on our handful of experiences here and extensive research for good deals, we recommend Around About Cars for rentals of a week or more and Avis (booked through a third-party like Expedia or Priceline for cheaper rates) for shorter-term rentals.
