I have 2 questions regarding Rav 4 Prime.......... ONE.. i tailgate a lot with my friends during football season..Probably not this season...Anyway.. Can the Prime or any plug in car be charged using a generator? TWO.. Im dumb about taxes.. How would a tax credit work? I dont itemize taxes just easy form.. Is this tax reduction taken off the price of the car or is it done at tax time when taxes are done? and If tax time, do i just get a refund ?
