I’ll do better than that. Here’s a near 30 minute video of Hall 52 Assembly building that only assembles your new X3 & the X4s. You probably already know this, but the X3 has the tall hatch back, and the X4s have the smaller, hatch. I like to call it the fast back hatch. ODD numbered X models have the tall hatch, even number X models all have the fast back hatches. https://youtu.be/jqbFudVVfFc?si=AuGzj-wZDCKEoES8
