hello all, new guy here. I've been wanting a Tacoma for a long time now and have finally found one to my liking. It is an '04 TRD 4x4. It has about 46k miles and is absolutely gorgeous. This will be my first one so I'm not too familiar w/ them, but when I popped the hood, amidst the immaculate engine I spotted what seemed to be a rusted header. Is this typical on Tacomas, even that new?
