Factory orders tend to tail off at this time of year with the change of Model Year just a couple of months away. Effectively a van delivered in July, before factory summer hols, has just one month before the trade classify it as a year old. Not really a problem if you're in it as a long term owner, but potentially a big hit if you sell relatively quickly. Waiting few months gets you a 2019MY van and a year 'til it's a year old as far as the trade are concerned. I hope the OP has negotiated a significant discount to take account of the lateness in the buying season.
