I have looked at the data from Mitshubishi as they left the country in 2020/2021 and just got back to the UK.
Mitsubishi had a peak in 2014ish with 60k cars. A year before they left, they were selling about 9k cars a year.
I've done the same check with Honda but I asked my dear gpt on steroids to think for 5 minutes and bring me the 10 years data for the UK.
