Hi Deborah,

It’s a little hard to know without seeing the cars. I presume you’re talking about a Qashqai? The most likely explanation is that one is a privately-registered car that has been sold and has now come back as a trade in, while the other could easily be a dealer demo, registered at the same time as the other, but which is being sold with minimal mileage. Or, of course, it could be a typo and the first car actually has 11,811km on the clock…
