NOT use the "drain hole" on the lower left in this photo. Not structural I think.
Suspension mounting points are always good usually. I think it depends on the work being done thought - i.e., if you're working on the suspension this obviously is out of the question.
Regarding lifting on the "pinch welds" - I believe the lift pads referenced do not actually lift on the pinch welded metal itself, rather on the material very near to it, thus giving the best strength possible. On an X1/9, that pinch weld is part of the very LONG longitudinal beam running from the front to rear and is
very strong.
End of the day it all depends... I've used the central front and rear areas
@kmead points out without issues. Changing a tire I've used the stock jack as well as a jack on the stock jack point without issue (lifts one side of the vehicle). I assumed this thread was about using jack stands to lift the entire vehicle and that is what my reply addresses.
