I just picked up a used 2018 Model S 100D; the car was in great shape but dirty; it looked like someone just got back from off-roading. The Interior had oily seats; the floor mats were muddy, the exterior was full of bird poops and leaves and muds. So I asked the rep, and the answer was that we are so busy these days, and we don't have a car wash service here. I thought the service was learning and improving, but nothing has changed!
