I would like to clarify exactly what the position is as regards Euro 6 emissions standards. My understanding, which agrees with answers you have given previously on the same subject, is that the deadline for cars to meet the Euro 6 standard is / was 1st September 2015. All new cars registered on or after this date - i.e. everything with a -65 plate - MUST BY LAW be to Euro 6 standard; no ifs, no buts.

However, I raised a query with a significant manufacturer on 2nd September 2015 asking why their website was still only showing information for Euro 5 cars, and I received a telephone call from them a few days later (all credit to them for doing this!).
