We have had exactly the same happen; we ordered on Jan 5th from Hedge End, told it would be there late May, possibly June. Based on that we sold our 33 months old Porsche Macan S in very late April and gritted out teeth for what we thought would be a few weeks with just one car. Sales person [MH, by any chance?] did not contact us as he promised to do, then began failing to answer our emails enquiring about delivery. It's only when I rang to get that question answered that we discovered that he had left months ago [writing this in mid May, now] and that our new NX 450h+ would be arriving in September [now mid July we are told....]. We've had new MBs [ S Class] and Porsche [911 / Macan etc] for the last 25 + years and never had this lack of attention. We also run, as the house run-about, a Ford estate and our Ford dealership is brilliant in every respect. So, for our first Lexus, we are not overly impressed.
