Whatever your decision, I really hope things will work out for you. I read up on the VW ID.4 and it is a nice car. It's about the same price for a base Kona EV SEL, but it includes auto-cruise control which I assume is like what you might get from the Ultimate. I think it's also all-wheel drive too. Yeah, really nice EVs are coming out in a few years....hence it is the reason why I didn't wanted to spend too much money as a first time EV adopter. That is why I did not want to buy a $50,000 Tesla to begin with.
As I, and many of you are experiencing, EVs are still having ALOT of problems. From range to battery management to charging to throttle clunking noises to spontaneous fires...all of the car manufacturers still need a lot of work to do, before we can get a relatively reliable, affordable, and long range EV. I am only thinking of keeping my Kona EV for about a few years (around 5) before I will upgrade to a better EV. I wanted to lease the EV initially, but since my commute is 100 miles/day, there is no lease for that....so I have to purchase it. I have no idea that the Kona EV will be having problems like this in less than 2 years. Hopefully in around a few years, they will have better batteries, and have the experience to analyze what they did wrong in their earlier designs....to come out with better vehicles.
Well, best of luck to you.
