All the options cost more.
When you decides to fix a mirror yourself there is a lot to consider. This company is prepared to sell you up to and including all the options. Most companies will sell you the cheapest option as your only option. When buying a mirror all you really need is a piece of glass. However if your vehicle has all the options you must pay for them. Folding (bedding), tilt, heated, auto dimming, proximity alert, turn signal and puddle lamps are all mirror options and must be considered for replacement when you buy a side mirror. If you buy and replace just the mirror you must consider whether or not you want heated and auto dimming. The thick black border around your glass tells you it's auto dimming. It's more expensive because there is oil between the panes of glass and electrodes are mounted around the glass in that large black border. All these options cost more but auto dimming, proximity alert and turn signal add between $50 to $150 to the overall cost. This company offers them all.
