They hand wash the cars. They handled MBs work, too. Yes, the OEM tires were trash. The Lx25s I replaced them with lasted about 50k miles though, as one would expect. With an awd car, you rotate the tires so as to prevent uneven F/R tire speed, so even more necessary on the OEMs. In fact, they opted not to rotate the LX25s knce or twice because the wear was even.Yeah, all those rotations and you still replaced tires at 16k miles. I'm betting all those "free" carwashes from the dealer, were the actual cause of your mirror issues. Those brushes are brutal!
