Owning an electric car is great until you are stuck waiting at a public charger in the rain. Charging at home changes everything, turning your garage into your personal gas station while saving you a ton on fuel compared to public stalls. Prices for equipment and installation dip a bit in late winter when contractors look for work.
We need to talk about negotiating the install before we touch any financing. Get multiple quotes from electricians and check your local utility company for hidden rebates before you buy the hardware.
Remember that the intro window is a deadline, not free money. If you still have a balance left when the 18 months are up, standard interest kicks in on the remaining amount.
