Volvo ex30 is the cheap electric volvo and is about to come out. The Polestar cars are usually more "sporty". Polestar used to be Volvo's equivalent of "amg", their sport division. Then Geely(the chinese owners), spinned it into its own brand, though obviously there are a lot of similarities between Volvo and Polestar.
I ended up leasing one as I wasn't ready to commit to EV, yet. It wasn't much more expensive than our Outback in monthly payments. Sticker shock on EVs is real, though.
