I've had my car long enough to need only a couple of washes so far, and I've stuck to touchless. They don't dry very well, so I spend a few minutes after the wash drying it myself gently with a clean microfiber.
I wonder how good a touchless do at cleaning after a long drive with bugs stuck in the front.
And when I take my care in for service, I'm definitely inquiring about their wash facilities before dropping the car off. I would assume that dealerships would be wise enough to handle these cars with care.
