A few notes on reassembly for E92.
1. The roof pillar trim panels are tricky. Make sure to align their plastic clips with the holes on the pillar, and that the plasic hooks at the bottom of the panels are locked in place when reinstalling the panels. Once this is done, you will need to tap on the panel to force the clips into their holes. If the clips are misaligned, they will get smashed (had this happen on the right panel). If this happens, no big deal - the panel will still fit in place just fine; you can order new clips in the meantime.
2. Side bolsters - when you pull them out, white clips at the top will stay in the body. You will need to transplant them back to the bolsters before reinstalling.
3. Make sure to not be in direct sunlight or you will be sweating like a pig which can be a problem given a rather tight space you are in. A portable fan blowing air in your face helps a lot
