Hi folks, I'm signing papers today for a new Black Raven 2009 CTS. I'll get a base car, the only options I'm getting is the automatic transmission and the wood trim. The car will not come with HIDs. I believe they are H11 bulbs. Does anyone with the base model replaced them with whiter\brighter bulbs yet ? I'm wondering if it's a big hassle like removing the bumper. thank you.
