I was really impressed with how quickly this ECM arrived after I placed my order. The unit was fully VIN programmed and literally plug-and-play, so installation went without a hitch. It saved me a huge amount compared to the dealer’s quote, which was exorbitant. The communication from the seller was clear and timely, which made the whole process very smooth. Overall, a fantastic experience and it got my S550 running perfectly again in no time.
