I'm currently in the market for a 4x4, 4-door, diesel ute. I do a lot of driving for work and comfort is a very high priority. If I drive a couple of hours to a job, my back ends up pretty sore, and I tend to need a massage once or twice a month, depending on the driving I do. Any help and advice is greatly appreciated.
Today's utes are all more comfortable than the boneshakers of old, but they still ride relatively hard because of the load they have to carry. The high-end models are generally more comfortable than the lower level models aimed more at the tradie, so perhaps look at those. If you're not concerned about brand, consider the Nissan Navara.
