That's what I have, but from Black & Decker - YouTube but it doesn't need a second car. Just fits in the cubby hole storage bin below the rear wind deflector. Smart thing to have if you get stuck out somewhere without another car around to give you a jump. Along with a portable air compressor, a can of flat-fix and plug patch kit, a utility knife, and a real lug wrench.
