One Hand Clapping points out
why the question "What Would Jesus Drive?" is a bad question to ask. (He’s referring to an effot by Christian groups to show that driving an "inefficient" car is somehow unchristian.)
One of the problems a lot of people have with organized religion in general and specifically Christianity is that it seems like religious authorities care little for the tenets of religion and more for their own pet causes. No one could ever know what car Jesus would drive, nor is such an effort anything more than a simplistic move that tarnishes the kind of work that Jesus would have done.
