Some feedback from our customers...
We did a North Namibia trip in June 2021. For almost 3 weeks we rented a HILUX from Odyssey car hire. The vehicle had about 70,000 km and was in perfect condition. I especially liked that the refrigerator was finally running stable and we had 4 brand new tires.
Excellent! Odyssey Car Hire is a local long standing familiy owned car rental agency. I have hired a car (Toyota Fortuner 4x4) from them for 3 weeks in May/June 2021 for a self drive tour of Namibia.
