Assuming a rate of return on the market of 10% is a little ambitious. You’re more likely to be around 5%. Also the depreciation piece being a matter of your opinion is gonna throw off any calculations you’d make. Supercharging also won’t be your sole method to charge as more and more chargers are popping up everywhere. There are a lot of different variables at play here but I think my main question for you is, do you want an EV? This post almost seems like you’re trying to talk yourself out of it. This is your car, and if you have the means to choose you should get something that you’d like and be comfortable in as opposed to what’s the best investment.

I feel like the challenge posed by the inventory is getting solved by lowering prices. I’ve seen some listings recently that have certainly been surprising. Nice to see now that I’ve started seriously looking to buy.
