I have not done any thing to the XR7 to speak of yet. It is showing about 65K miles and it drives like that is the correct mileage. It has been repainted the darked green, It was medium lime green(Lime Frost) and looks good from a few feet away. I can see sanding marks in it. But it will do for a few years untell the 69 390 is mearly done. Neal.
