Last weekend I was looking over my new to me, 2013 STS SE5 to see how involved doing my own fluid changes would be. I usually do them on my cars and Harleys before this. Side panel removal, no problem. Drain for the oil tank and transmission filter, easy. What is the trick for taking off the bottom panel to allow reasonable access to the engine drain and the oil filter? I took out the Torx screw on the left side. A part of the bottom panel clips over a frame member. After that, I could not find any way to remove the panel. It would slip forward and backward maybe a half inch. I saw the black posts where the panel slid on, but I could not find any way to remove that panel. I did not want to force anything too much and break it.

The Spyder was flat on the garage floor. Does it need to be up on a lift of some sort a minimum amount? I have to be missing something. Photos in the Owners and Service manual are almost useless to see. Manuals make it sound like a piece of cake.

Thoughts or solutions?
