I purchased the 2020 GMC Terrain 2.5L ECM from this seller and was really impressed with the whole experience. The unit arrived quickly with free shipping, and it came already VIN programmed, which saved me a ton of time. Their customer service was very responsive and answered all my questions promptly, making the process smooth from start to finish. The ECM worked perfectly right out of the box, and my Terrain runs like new again.
