Hi guys! I'm a bit new to the Prius family, so I was looking for some advice from some of you guys. My commute is currently 50 miles one way to downtown Chicago and I drive a 2002 Toyota Corolla that gets about 30mpg. I was looking to save fuel costs and was considering either a Prius C, Prius, or Prius PHV. My home is only about 4 miles from the highway and my work is about 0.2 miles from the highway so basically all my driving will be highway (I-90). Now I have a question, which car is most cost effective? The Prius C and Prius are less expensive, but then I get lower fuel mileage than the plug in. My questions are: 1.) If I bought the PHV and since I'm going to be driving in heavy traffic, would it be better to save my 15 EV miles until I reach the traffic and drive HV in the non-traffic areas? That way I am using zero fuel while sitting in traffic? I don't have a charging station at my work, the closet one is about a mile away. 2.) From solely a cost stand point, which car is better for the cost of the car + fuel mileage for a 100 mile commute? The Prius C, Prius, or the PHV? How long would it take to break even on the extra cost of the PHV based on fuel savings? 3.) Any other buying advice would be greatly appreciated! Thanks!
