Just found this site and it's great to see the G6 has a big following. I'm an aviation mechanic in NC and am the original owner of a 2006 white 6-speed GTP coupe. Bought it on new years eve 2006, but it was raining and I emphatically told the dealership there was no way I was going to drive a brand new car home on a rainy night, so picked it up the next day, a sunny new years day. The first day of having a new car carries a reverence akin to a honeymoon.
Anyway, it's been a great vehicle that I thoroughly enjoy driving. It's still a knockout to look at and I get compliments all the time. It will be fun to compare notes. I hope I can help other's from my experiences as much as I get knowledge from other's.
All the best,
