First you should find out/ask how strong the pinch weld is on your vehicle. And is that area rusty? Now all vehicles are strong in that area.
Second look at the factory jack and see how it engages the pinch seam.
Third when you bring it some place for service they are just going to lift it at the pinch weld area.
I was told by my mechanic that my Subaru is very strong in that area. The factory jack actually has a deep enough slot that the vehicle is lifted by the metal on either side of the pinch weld, not the bottom of the pinch weld.
