I ordered the 12590647 ECM for my 2005 Cadillac CTS and was really impressed by how quickly it arrived. The unit was already VIN programmed and truly plug-and-play, which made installation a breeze even though I’m not a professional mechanic. Compared to the huge quote I got from the dealer, this saved me several hundred dollars, which was a relief. The communication with the seller was clear and helpful when I had a few questions beforehand. Overall, this service was efficient, and my car runs perfectly now thanks to the smooth replacement process.
