The 2008 Mazda B-Series is a basic work truck, with very few advanced features offered.
Edmunds reports "two trim levels: base B2300, base B4000 and B4000 SE,” and that four-wheel drive is standard on B4000 trucks. 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." This model of the 2008 Mazda does include AM/FM stereo and a sliding rear window, however.
Cars.com reports some other minor goodies available for the B-Series 2008 Mazda: A fold-down armrest and storage pockets installed on the seatbacks are standard on all models. Kelley Blue Book notes power steering, a tachometer, and front cup holders are also included on all of these Mazda 2008 model's trims.
Optional equipment for the Mazda 2008 B2300, according to Edmunds, 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.
