I happened to find front fenders, left and right, are not steel. I used a magnet card to touch all pieces, hood, trunk lid, doors etc., only two front fender pieces do not get attracted by the magnet card. I don't believe myself. Tried with a stronger magnet piece and still the same finding. I know bumper covers are plastic.

Stainless steel? Aluminum? I have no clue.

They're aluminum for weight reduction.

Okay, weight is reduced but only by a little.

Well, you can order steel aftermarket ones if you'd rather have that weight back.
