the next quarter starts 1st april in theory that would be the next price point but these days changes happen all the time. ev4 gt-line has been removed and will probbabley come back at a higher price even before 1st april. so if something your interested in is a good price on 28th feb i would sign up for it.
i have the same date for ordering and i will order something on that date to guarentee that price and trim.most dealers will adjust if the price goes down, and if something else appears that suits you better you can cancel and reorder that.
i am down to a choice of 2 ev4 air and mini monochrome, i would consider channging from either of those for the ev4 gt-line but i cant see it coming back at 0 ap for wpms. i wish they would guarentee the price for the quarter but manufacturers will take popular stuff off motability to fill retail orders after all theres more profit in them for the manufacturers.
