Green one is a Polaris 90, 2-stroke with electric start and newer battery, all brand new tires, brakes are descent but not the greatest, racks and plastic are broken in spots but great running little machine. Red one is an Arctic Cat 150, 2X4, 4-stroke with electric start, automatic with reverse and a brand new battery and fresh oil change, runs great with 1760 miles. The kids have outgrown them but they were a ton of fun. $1000 for the Polaris and $1800 for the Arctic Cat, or package deal for $2250. Thanks.
