At a local Cars and Coffee get together a few month ago, there was a Kirkham 427 that was unpainted, kind of dirty, wheels had brake dust on them, engine wasn't bright and shinny... you get the idea. I liked it and I usually don't like unpainted cars. The body was what I would describe as oxidized brushed. Beyond filed for sure but not polished! It had a 'used' look to it, a couple road scars, a couple small dents but it was pretty cool! Only thing I didn't like was the polished stripes but whatever.
