Model 3 reservation holder here and just trying to estimate the costs of owning one. A cost I assume that will be significant for me will be the windshield since the car will be used for highway travel 90% of the time (40k km annually), in Edmonton, AB, where a bunch of sand (and rocks) are always on the road. Our current vehicle, we have to replace the windshield every 2 years. Currently a normal windshield replacement for our vehicle is only $250-300 CAD. Has anyone replaced their windshield? If so, is it around $1500 USD? What's everyone's thoughts on aftermarket windshield options becoming available once hundreds of thousands of model 3's are on the road? Think the price will drop significantly?
