If you're on a strict budget but still want to take advantage of the Prius' 50 mpg, this is the package for you. It features the same Hybrid Synergy Drive found in all the other Prius packages, and also comes with Toyota's comprehensive Star Safety System with traction control. The Prius Two comes with cloth seating, an AM/FM/CD/iPod touchscreen stereo unit and Bluetooth, but you may find yourself pining for some of the advanced features from higher trim levels.

For just $1,565 more than the Prius Two, package Three makes a great hybrid a whole lot more interesting on the inside. Upgrading to the Prius Three brings navigation and Toyota's Entune infotainment system with its advanced smartphone pairing capabilities, large collection of audio sourcing options and slick voice-controlled interface. You'll also get convenience features like keyless entry and push-button start. There's a big jump in price before the next trim level, so the Prius Three is really the sweet spot in the lineup for a large number of buyers.

The Prius Four is a stepping stone up in the lineup, bringing more standard equipment than the Three while opening up the more- advanced options if desired. Toyota spices up the car's interior with SofTex seating and trim, which has a leather-like feel while being easy to clean and completely earth- friendly, and a sweet-sounding JBL Greenedge audio system. You'll get the standard navigation and Entune and projector-beam halogen HID headlamps, but top features are grouped into the additional-charge Deluxe Solar Roof package ($3,820).
