i use to own a 84 cadillac eldorado biaritz, very very nice ride. the thing that made this car, or the biaritz in general, was that the car besides many other special options had a stainless steel roof the stretched from the end of the vinyl roof to almost the edge of the wishield. anyways in my many many years searching salvage yards i at a few points in time would find a g body car that had a stainless steel quarter roof cover that pretty much sat where you would normally see the vinyl top. has anybody else seen these?? were they factory or maybe dealer installed??? i dont know if i would put one on my car but if i find another one i am going to snag it. i am going to search for pictures tonight
