Well, I'll be......
 

Was rotating the tires (5K mark) on my '16 LaCrosse. Yes I can have done but I want to know jack points, lug nut tightness, tire weight etc. I won't call AAA for a flat (how embarrassing).

So I lift up that big heavy velcroed trunk pad (for tools) up and was wishing I had a prop Rod. Well there's a finger slot to raise that up with also. All of a sudden it unsnaps with a angle piece that you can hook up on the trunk lid edge where the gasket is. Perfect, well who would know that. Buick, well done.
