Hello all,
Car is back on sale. I had marked this as 'sold' as a potential buyer had left a deposit to pick up at the end of the month, but when the end of the month arrived, I couldn't get hold of him. Think they have even blocked my number

Odd. Just tell me you've found something else, it won't hurt my feelings.
I have amended the first post to have more clarity, along with a walk around video.

Have you heard anything back from the dealer?
I reached out to the dealership I purchased the car from, and they provided a clear NMR Report, which I have attached. I trusted their report, as multiple dealerships I contacted for potential part-exchanges did not detect any issues during their checks—they were only made aware after I disclosed the discrepancy. I have attached it in this post, and it's also on the first post.
It's worth noting that the same MOT garage conducted the tests in both 2018 and 2019 when the discrepancy occurred, which is somewhat reassuring as it wasn't a one-off 'friendly' establishment. I contacted the garage, and they acknowledged their error but conceded that it was too late to make amendments on the official record.
I also submitted an application to the DVSA to correct this issue, but it was rejected due to insufficient evidence, likely because there is no receipt or invoice available to confirm the actual mileage in 2019.
Also apologies on the 'full service history' thing, I'm not too experienced with selling cars and terminology. I have changed it to 'service history'. It does have plenty of paperwork and has been serviced within 10,000 mile intervals and that was good enough for me. It also has records of VANOS maintenance around 15,000 miles ago. I'll get a scan of that if it helps.
All this being said, I have priced this car extremely competitively at £12,500 to ease any sleepless nights the discrepancy may bring. In my opinion, it represents an excellent deal for a clean, well-maintained vehicle with low mileage. Additionally, I am open to negotiating for a quick sale, as I am eager to move into a 5-door vehicle as soon as possible.
