4.0L 6-Cylinder DOHC 24V. CARFAX One-Owner. 2011 Suzuki 4.0L 6-Cylinder DOHC 24V Sport Equator 5-Speed Automatic Red Clean CARFAX. Reviews: * Suzuki's Equator stands out in a crowd for all of the right reasons. The Nissan Frontier, on which it is based, has long been regarded as an overachiever in the segment. The Suzuki is - to most eyes - the more attractive iteration. Get it if you like looking at your vehicle before positioning yourself behind the wheel.
