It feels a bit like manufacturuers make it just a bit mroe difficult than it should be to jack cars up these days, BMW also don't make it easy to find structurally sound jacking points outside of the sills. I presume it's to force the causal DIYer to book it in ratehr than risk unintended damge.
I'm talking about soeone who is capable of doing oil/filter changes but doesn't have the skill to take the head off. If you're wary of where to jack the car up it's probably just enough to make you not do it...
I don't know if I'm just getting old, but it seemed so much easier when I was in my late teens/early 20's...
