There’s an all-new Sentra coming in 2007, so the 2006 model gets only minor upgrades. The audio system in the Audio Fanatic Package gets an in-dash 6-disc CD changer. Two exterior colors are new for 2006: Sapphire Blue and Sunburst, the latter of which is new only to the 1.8L “S” model. The fifth-generation Sentra remains a popular choice for buyers looking for driving fun at an affordable price.
