A few miles but not very old and has the Icon lights, aluminium trim wouldn't be my preference but it's personal choice: https://www.autotrader.co.uk/car-details/202108166304544
This does appear to be the least terrible option but wow, 80k miles and still 25k. Ignoring the mileage the spec is really quite nice which is often rare on a G31.
If you can possibly avoid buying a car at the moment then really, really do so.
My plan when I bought my F10 530d at 1 year old in 2016 was to run it for 5 years and and then replace it with a 1 year old 530d again, or perhaps something similar if things had changed. At one point I thought an M340i would be nice. I've well and truly shelved that plan.
