 Traded an 07 Buick Lucerne CXS in on this Azera about a month ago.  I had been researching and test driving earlier versions of it.  Traded it in on an 08 Azera Limited with the Ultimate Package.   The Azera is a driver's car; it performs and handles excellently.  I have added mp3 (wireless) and a lip spoiler, etc.  Gangbusters.  SemperFi
