The 2009 Mazda B-Series is a relic in terms of features. However, the base model of the 2009 Mazda does include AM/FM stereo and a sliding rear window.
ConsumerGuide tells us that four-wheel drive is completely unavailable for the 2300 trim, as does Edmunds: "The B2300 comes only as a two-wheel-drive regular cab." Edmunds reports "two trim levels: base B2300, base B4000 and B4000 SE,” and four-wheel drive is standard on B4000 trucks.
Kelley Blue Book notes power steering, a tachometer, and front cup holders are included on all of Mazda 2009 model's trims. Cars.com reports some other minor goodies available for the B-Series 2009 Mazda: A fold-down armrest and storage pockets installed on the seatbacks are standard on all models.
According to Edmunds, optional equipment for the 2009 Mazda B2300 includes "foglights, skid plates, a limited-slip differential, 16-inch alloy wheels, upgraded upholstery, cruise control and a bedliner"; these features are standard on the B4000. Features like iPod and Bluetooth connectivity, as well as power sliding rear windows, are unavailable.
