I’m not sure I see anyone expressing pride at how little they drive the car.
I also think you need to account for where people live. My best case is a 7 month season. I’ve have averaged 2,100 miles per year since I acquired my first 4C 3/6/16 (that’s precise, I track it, lol). That’s 300 miles per month. I am also 37 and work 50-80 hours per week.
You had a down year in 2021 as well but you said your good years you average 6k km, or 3,600 miles. IIRC you live where you can drive year round so it’s the identical 300 miles a month I do. IIRC you are also retired (I’m jealous) so why aren’t you driving it more?
I’m not trying to pick on you, btw. I’m not sure I agree that people are proud of how little they drive, though. I am a big fan of yours actually, so please don’t take it personally. I’m just trying to make the point that a lot of this is contextual and simply saying a # of miles doesn’t tell the whole story…
