In the middle of a 1400 trip in our Sprinter Van, caught in a terrible downpour, both headlights would not come on. We dropped in unannounced hoping for service. The Sprinter service coordinator, Gary Patel, did not have a service technician free, but diagnosed the problem as likely just two bulbs burned out; "Simultaneously?", I asked. "Yes, I've seen it before." Sure enough. He was not only correct, but put in two new bulbs, refused any payment, and had us back on the road in minutes. We have had good service at MB dealers all over the country, but this was exceptional.
