I was really impressed with how quickly the 2004 Infiniti Q45 ECM arrived—shipping was surprisingly fast, which helped me get my car back on the road in no time. The unit came already VIN programmed, so installation was straightforward and truly plug-and-play. I’m relieved I didn’t have to take it to the dealer, as this service saved me hundreds of dollars. The communication from the seller was clear and professional, answering all my questions promptly. Everything went smoothly, and my Q45 is running perfectly now. Definitely a great value for the price.
