I've been researching new cars and the Prius has caught my eye. There are lots of things I like about it, but was hoping I could get opinions from people here on MR. (Since we are all appreciative of good technology ) Here are a few questions... feel free to answer some/all/none. 1. In your experience, what is the realistic gas milage? 2. Do options like Smart Keyless Entry and Navigation make the loaded Prius worth 25K? 3. How much can the MSRP be haggled down (if at all)? 4. How well does the car perform when loaded with 4 people + stuff? And PLEASE, if you have any cons or disappointments with the car, tell me!! I'm sure not going to hear any from the dealer. Thanks!
