I highly recommend Harper's. I must admit I was hesitant after reading some reviews but I went ahead and rented a 4x4.

The agents explained to me there were those that damaged the vehicle, not intentionally. When they were off-roading, they scraped and dented the undercarriage. When I returned my 4x4 rental, I was nervous when they were inspecting. But it was cleared since I didn't do any off-roading.
