I drove a Bolt EUV yesterday. It's a credible Kona EV replacement.
The handling was a pleasant surprise: about as nimble as the Kona, and much better than the Mach-E. It has true one pedal driving: stop and start with just the accelerator pedal. I found the seat a little less comfortable than the Kona, but the 8-way power adjustments helped.
Features in the fully equipped top Limited trim are almost as good as the Kona Ultimate. Both have rear proximity alert, rain-sensing wipers, adaptive cruise control and the usual automatic safety features. The Bolt EUV adds a 360 degree parking camera, and the inside rear view mirror can switch to display the wide angle rear camera view. It comes with a 120/240 volt charge cord that delivers up to 7.2 kW, making a separate EVSE unnecessary. But the Bolt lacks HUD and cornering lights, and GM still hasn't twigged to Homelink, an omission Volt and Bolt owners have been lamenting for ten years. The blind spot alert is unaccountably only visual; no warning beep.
The instrument cluster is configurable and useful, with a digital speed readout larger than the Kona's and not blocked by the steering wheel like the Mach-E's. That and the option to display the speed limit from the nav database would make up for the lack of an HUD, but only if the nav/sunroof/sound option is purchased. I like the display of instantaneous battery power in kW.
The EUV has just started arriving this month (June) but it looks like there will be plenty of supply. The dealer had a $4k markup sticker but the salesman thought they would be selling at MSRP within weeks. The fully equipped top Limited trim with all packages lists for $43,190, but I'd skip the Super Cruise prep option (lane keeping on pre-programmed highways), taking it down to $40,900, and probably the sun roof, nav and sound system, so $38,495. Android Auto uses the full 10.2" display so a nav system isn't necessary. Add $7,500 because GM no longer gets the federal tax credit

, but deals might become available soon, and Costco Auto offers a $1000 incentive on 2022 Bolts ($3000 on 2021's) through August 2.
I was leaning toward the Bolt EUV at $8,000 less than the '21 Kona, but the tax credit, HUD, and slightly better safety warnings are swinging me back toward the Kona. At least, that's how it stands today.
