It is pretty much as ZheWiz said, at the end of the day it is what you need and want. when I bought my diesel I wanted the diesel, could have gotten the v6 as it would have covered what I need. I grew up and learned to drive on an Isuzu 3.0l diesel and wanted a diesel for myself. When I moved to Canada I was dissapointed due to the lack of small diesel options available, and that the options available was not what I wanted, as the trim options available here was what is on lower versions what you get in South Africa. Test drive all, and decide what you want and need. All will have some advantages over the next, and their own problems. The problems that I had with mine could happen to any one of them, due to none was related to the engine directly.
