Thanks GLANGA! I also own an 05 Redline VUE and the bulb replacement on it was very easy, but it doesn't look as easy on the CTS.
I just purchased my fully loaded 08 CTS, eventhough I had also considered waiting until the fall - for the CTS-V. But, after seeing the recently posted MSRP of $79.500, I changed my mind. I truly like it and want it, but $80,000 is a big piece of cash! At any rate, maybe I will just wait until next year and purchase the 2010 CTS Coupe for myself. Our current CTS is more for my wife.
But, I will keep in mind your suggestions and will definitely post pictures afterwards. Thanks again!
