You can get by on public fast chargers for the interim. 120V is also more viable than I expected. I was all ready to install a 240 line for a charger when we bought our EV but a year later we haven’t actually needed to yet. No long commute in our household, so 🤷‍♂️BTW we did exactly what you described: bought a very low-miles used Bolt on Carvana. Take the plunge if you want to.
