Hard to think through the solution to this.

In the event it is the subframe, to get it fixed would probably mean a long time paying it off.
I can't just scrap it and get a banger because I need adaptions to legally drive, which would probably be about the same if not more than the subframe for what I need.
Scrapping it and being without a car means a total loss of independence since I can't navigate transport most days.

A few things that are making it a bit wtf:
someone I know who works almost exclusively on beamers has never seen a subframe fail on this model without something catastrophic happening
It's a /bit/ higher on one side, so could just look low from taking all the weight? Idk
There's still some bounce in it.

I'm not going to actually get any answers until we can jack it up and have a look or get it to a garage since I don't think our trolley jack fits under this car anyway 🙃
