I was really impressed with how quickly the ECM arrived—shipping was faster than I expected. The unit was already VIN programmed, so installation was straightforward and totally plug-and-play. This saved me a ton compared to the dealer’s quote, and the communication from the seller was clear and professional throughout. Definitely a smooth experience from start to finish.
