All stock no rot at all. Runs so good that I don't have the heart to tear it apart, don't really know what to do with it. I bought it cause my wife saw it and said : " Oooh Honey , I like that car ! If you bought it I would drive it ! " Well I bought it , did a little fixing, she drove it once and hated it. Said it was too small and too slow. Gas is going up again, so I'll probably pop a battery back in it and start driving it again, it gets almost 40 mpg.
