As far as drunks building cars, see the link below for the JD Powers 2001 Initial Quality results. The Intrepid had the highest score of any domestic nameplate. Impala did well too, but apparently the Malibu is not on the list. Not sure why or where it would finish.
Time will tell on the quality, but the Malibu is not exactly known for it's stellar reputation in that area, but not a bad car either.
My 2000 Intrepid R/T came right in on the average, I had one problem from the factory that had to be fixed.
Now if GM could just find the time to actually build a full size rear driver, I would be interested.
