The Toyota Yaris is a lightweight car that gets 40mpg and costs 10-12k. The design is simple and includes some extras like plenty of glove compartment space and audio-in jacks for an MP3 player.
It's worth checking out the 3d tour (you can see a screen cap below) -- it's one of the best walkthroughs of a product I've seen. The animation is smooth, the lighting is perfect (similar to David Fincher's video for NiN's "Only"), and you can interact with details of the car's features... like checking the glow of the dash or peeking under the armest. It introduces you to the car in the same way you might explore it in person if you were checking it out for the first time. It's a rare example of a website helping a customer get a sense of the details of a product instead of simply listing the facts.
