Benjamin Cooper –
I purchased the 12596263 ECM for my 2005 Cadillac CTS and was really impressed with the plug-and-play setup. It arrived quickly with free shipping, which was a nice bonus. The unit was already VIN programmed, so installation was straightforward, and my car runs perfectly now. Customer support was also very responsive when I had a couple of questions before ordering.
