Yes, the S63 each time, unfortunately. For convenience I get my tires from MB. I pull up, tell them the problem, and 5 minutes or less later I drive away in a MB loaner - C, E, or GLK. They deal with locating the tires and call me when the car is repaired and all cleaned up. Didn't hear from them today so I hope to pick it up tomorrow; if not, I'm not concerned because I still have the loaner. Excellent service from the MB folks.
