I am a new Cadillac owner. My new ride is an 05 STS base v8 with silver paint. It has 147000mi. On it and in my first week of owning it, it had new valve cover gaskets, new plugs, and new coil packs installed. No more check engine issues. It runs like a scalded ape. I love this car! I hope to get my hands on a STS-V when I finish paying off this car.
