Don't go for Mazda or Ford, the same crap you will have on maintenance, Mazda has lot of issues with their cars in the hot climates of GCC. Ford is ford, not reliable, unless you get their trucks. For jeeps, only go for Wranglers and Cherokee, Dodge services are done through Al Mana, they are ok. Mitsubishi Pajero and Pajero sports are reliable too, you can see a lot of them around here. But best will be Toyota, try FJ Cruiser or Prado or Fortuners. With nissans you get hits and misses, sometimes good and sometimes bad, their parts are made in various places, not all from Japan as everyone thinks.
