2002 Infiniti G20
When released, this upscale reworking of the Sentra was considered too similar to its little brother from Nissan. These days, if you can find one, you can get a premium badge and more features for less than you'd pay for a similarly sized but more pedestrian used car. Handling in the G20 is better than the Sentra, and it's much better looking as well. Kelley Blue Book Retail Value as of December 2011: $5,965.
