Figured I'd introduce myself here. Name's Trevor and I just picked up a pre-owned 2006 Grand Prix. I know there's a lot to be learned when it comes to new cars and this seems to be the best place for Grand Prix owners. I look forward to scouring the forums for good, tried and tested, and more importantly, peer-reviewed information as I've already got a few modifications in mind.
Thanks in advance for your fellowship and advice.
