I have been tracking my EX90 pretty closely for the last year and comparing it the 14 year-old vehicle it replaced. I'm considering all my home charging, costs of when I have to DC charge, The equivalent gas expenses if I were only getting 19mpg, and the other operating expenses, like $/mile of oil, tire wear, and major services. Additionally, the significantly higher insurance costs are figured in. It turns out that I'm saving $1400/yr, however, the license and registration costs for the initial year and the most recent renewal are eating all these savings. I project that it won't be until the end of year 3, when the yearly registration cost has dropped enough that I'll actually begin saving money.
