I paid Tesla $3k to upgrade my 70D to 75D over the air. 6 months later they dropped the price to $500. I didn't b1tch. I understood that is a risk you take when you buy a depreciating asset. And I didn't buy this depreciating asset because it was wise financially. I bought it to support Tesla's mission and because I like technology, EVs, road trips, and autopilot. I'm willing to take the depreciation hit to enjoy such wonderful technology. Worth every damn penny.
