I can't believe I watch the whole 6:24 video of your car being washed!
It was very interesting though for some reason. I guess i was trying to compare it to all the carwash places i have gone to before and comparing the subtle differences. Seems your wash gets better coverage and dries way better than the ones I been too. Would have loved it for my old truck. By the way I hand wash my 1er too and would never let that touch it.
