Pros: We were happy with the service and the vehicle in general was good. We did find our vehicle a bit squeaky and the shocks could have been replaced. Having seen the roads though, we understand why the vehicle was in the condition it was. The service was great and he took pity on us when he realized we weren't expecting the extra $800 in insurance and he threw in a GPS, which was a total life saver.
Cons: Please be aware that the cost of the vehicle rental does NOT include the insurance. The rental was estimated at $150 but when we got there, the mandatory insurance coverage took the total cost to $920 CAD. We had read about this, but we thought the credit card insurance covered it. With all the information printed out and in hand, we realized no cards will cover third party liability - which is mandatory there. The options were to put thousands down as a deposit and pay for any / some damages, or get full coverage for MUCH more per day. Please keep this in mind when booking a vehicle. And a 4 wheel drive is an absolute must if you want to drive any of the 'roads' in hard to reach but beautiful places.
