BMW Northwest will do a hand wash if you request it. Of the 3 I had done there, 2 were acceptable.
BMW Seattle will do a hand wash if you're willing to pay for a detail. Otherwise it's drive-thru. I highly suggest you specify no wash.
For those that are in/around Fife, the new car wash near the Emerald Queen is pretty impressive. I wash my MDX there. $8 covers it. There are no upgrades. You get the full meal deal for $8. It has a machine that applies tire shine at the very end as well. Once you pull out, there's a full row of vacuums that are free to those who have paid for a wash.
