 I made the mistake of trading a 2007 Avalon for the 2010 Altima for better gas mileage and on the basis of a favorable rating from Consumer Reports. The Altima's "premium" Bose sound system has only a single-disk CD player, but worse than that, the car suffers from engine noise and rattles. It goes over bumps like a tank. The various electronic displays for temperature, mileage, and so on are widely inaccurate. In short, the car is a major disappointment, and I shall unload it as soon as I can.
