I did a fair amount of research before trying to jack up the front of this car. I watched some videos of people jacking up similar (but not identical cars), and I pulled this image from the web:
Nothing matched exactly, but I thought I had a good enough idea of where to place the jack and began lifting the car.
Half way through the lift, the jack suddenly moved sideways. It didn't lose contact with the car or drop it, but something had suddenly shifted. Concerned, I immediately lowered the car and saw that I had bent the piece of metal I was lifting against.
So what damage have I done here? Is this fixable? Is it safe to ignore?
And most importantly, what's the correct way to jack up the front of a 2005 Mazda 6, since what I did here is clearly not it?
