Im looking at a Turbo T 4 sale. One of the previous owners put a GN spoiler on it . Needless to say, if I bought the car, it must go. What attaches the spoiler to the trunk and tops of the quarters? Does it bolt on, or did they glue/sticktape it on? The spoiler appears to be OEM equipment, possibly dealer installed, and not aftermarket, if that helps.
