would like info on 1999 cadillac deville phaeton editon

I am hoping some one can help me out in getting some info on the car i just bought because it is apparently a special release.  I have never heard of the Phaeton edition and i cant seem to find any info on the 1999 release of the Phaeton.  I have found several older releases of this model but nothing past 1978-79 which doesnt help me.
 
Thanks

If memory serves me correctly there was a phaeton "package" on the 94-99 coupe deville and sedan deville.  I haven't been able to find any info yet.  Still checking.   Good luck.
