Hi, I'm new here... I am trying to buy a new Prius, but am having trouble getting knowledgeable assistance to make decisions to do so. The first problem I have is that can't decipher why thre are three base models, what the difference is. I am pretty sure we want the touring edition, even though the dealer told me it "only has bigger wheels", but I'd like to know, on the Toyota website, why the TE shows to be a "4 door" and the other two show to be "5 door"s. Also, I have no idea why there are two 5 door basic models listed nor why there are different prices betwen the two. Any help is greatly appreciated!
