We have rented a Mitsubishi pajero 4×4 during 24 days by Speedy Muscat. We drove 5000 kms on roads, tracks, Gravel roads, mountain, deserts, dunes, beaches. (Very bad tracks everywhere in Oman) and never we encountered a problem with this car. Tires and engine was very good. the price was also very good compared to other companies and the staff was very friendly and honest
