To start with, Zancars are the perfect choice. Good car, great price, fantastic service and more.When abroad, I always like to rent a car or bike to explore. After being a passenger through Stone Town I was a little hesitant about whether renting a car would be a good idea. But I wanted to explore and taxis here arent cheap. If you want to explore, renting a car is far cheaper and gives you all the freedom you need.Some advice for you. Drive slowly and very carefully. Potholes are everywhere, speed bumps are everywhere else. Pay attention to vehicles behind you that will want to overtake with less room than they would at home. Let them pass you! Watch for scooters and bikes to your left. Country roads are mostly pretty easy, around Zanzibar City at rush hour is pretty hectic...You may here about corrupt police pulling some drivers over. This happened twice in the North, but not in the south. It is nothing to worry about. The first officer that pulled us over was actually very very friendly, asked where we were going, gave some driving advice, and then asked if we wanted to make a small donation. We gave a small token. We were pulled over later that day and accused of speeding. Just call Zancars immediately and they will sort out for you. Make sure you have the right paperwork. Zancars will sort this - your drivers licence and the local permit. Then you have nothing to worry about.Zancars were faultless. The car was great, the price was great. They delivered to our hotel on time as requested, and collected back from the hotel for just $15. No hassle, no attempts to say I had damaged the car in any way (which is always a worry - though do always take pictures on collection to protect yourself). It was a great experience. I thoroughly recommend Zancars.
