Are people going to hold off buying until they can get a 2020 plate on their new car?
The talk now is starting to turn towards next year as analysts and experts wonder and ponder if more people are going to hold off buying until they can get a 2020 plate on their new car.
Just how much the 'new-decade reg' will impinge on the public consciousness remains to be seen.
It is only March after all.
But it happened in 2013 when the prospect of owning a car bearing the superstitiously charged '13' plate deterred estimated thousands from buying.
And now, amid a perfect storm of more people buying used imports, Brexit uncertainty and doubts over diesel's future, the real prospect of people deciding they prefer 201 to 192 on their new motor.
New-car purchases are slipping month-on-month and year-on-year as you know. And the reasons for it I've already outlined.
But this year may be different - or certainly the mid-summer 192-reg season could be, sources are speculating.
It didn't happen so much in the last 'decade change' (2009/10) because the number of new cars being bought was low due to the raging impact of the recession.
This time around, however, there seems to be a sense that some people are waiting anyway to see what happens on so many fronts that the new-decade registration number is a final, possibly decisive, factor to consider.
Do you still plan on buying a new car this year, holding off because of the registration period, or are you waiting anyway?
