All good posts above. Like all things they all have pros and cons.
Jeeeps are fun , exciting, great views, cheap, give access to tracks through the mountains.
But they are slow so a drag if doing long distances, tiring, heat and sunburn a problem in hot months so trousers, long sleeve shirts, hats which stay on in the wind and glasses all good to have with you. you cant leave valuables in the jeep when away from it, not much storage space, you get very wet if it rains. A canopy wont keep you dry !. potholes and speedbumps are painful if you hit them at speed
Having listed all the negatives we like jeeps as the positives outweigh the negatives for us .....but then we ride motorbikes so we are used to hardship

Cars with air con are less hassle , more secure , safer, less tiring for long journeys, but reduce the sense of a holiday "adventure"
