Spot the problem
I've never had suspension go both sides at the same time before. That's a new one.
My money is the subframe failed
I was really looking forward to going for a drive today too 

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.

@babe Whoa. Both sides going at once…I think I’ve only seen that when someone has air suspension or with a catastrophic event like hitting an absolute crater of a pothole at high speed. Was it noisy on turns for a long time?
@monkeyninja Nope, drove like a dream about 2 weeks ago. No bumps, no groans, no suggestion anything was wrong

@babe Damn, only thing I can think is that there was major corrosion. We’d sometimes see that when I lived where salting the road in the winter was common and the salt corroded the metal.

Not having air suspension, corrosion is the only thing I can think of that would make sense. So likely one gave way and that canted the suspension on the other side forcing it to give way as well. You may have the right of it with it being subframe but I’m hoping it’s corroded springs as that’s at least more fixable.

At least it happened while it was parked instead of on the move? That could have been terrifying.

@monkeyninja yeah hear that about e36s the rear struts giving out but on a newish 6? series id be surprised
@sangu Right, exactly. You know...it's also possible that only one collapsed and the other is just compressed heavily. I could certainly see a possibility where if the suspension already has a lot of play and one goes catastrophically that the other might compress under load and make it look like it had failed at the same time. I mean...I'm taking guesses here obviously. Getting the car on a lift to see what's going on is really the only way to know for sure. But hopefully for the sake of @babe it's something reparable.

@monkeyninja @sangu That's looking more like the case.
There's just under an inch difference each side, so looked like dual failure, but there's only a few inches off what it looks like normally anyway, so it's probably one failed/one compressed.

Someone's kindly had a look at the model and spring seems the most likely point of failure. Will find out soon enough I guess!

@babe @sangu Damn, but hey at least that's ideal right? It happened at rest so the likelihood it did frame damage is lower a bit. It's a shitty thing to have to deal with but hopefully if it's just the one and there's no subframe damage, it'll just be a quick trip to the shop for repair and you'll be back to driving again in no time.
