That looks like a nice stand, I like that it's flat on the top as well. I always found the cutout on the classic stands always was too deep and damaged the body work if you try to put it on the pinch weld.
That door panel should buff right out.
I have Harbor Freight floor jacks, and so far so good on those.
I have 2 sets of these aluminum jack stands. Cross pin, light weight, flat base to not chip concrete.
