My Polaris Ranger didn't come with any mirrors. We park this in our garage and drive on the street so we needed a mirror. I got this mirror on Amazon for a good price and the install is pretty fast. The mirror does vibrate when parked in idle, but I think all mirror will do this as the chassis vibrates when the engine is one. Overall great purchase.
