So I decided to start changing the oil myself in my '05 GTP, and I get under the car to find an almost rounded out bolt. There was no way that thing was coming off with a 13mm socket or wrench. Anyone else run into this, and what are the options? It's not exactly an easy bolt to maneuver around with the tranny pan right there to try and use a "bolt out" socket. I may just have to cut my losses at this point and take it to the shop to see if they have the tools to do it.
