They did an absolutely perfect job prepping my car when I picked it up at delivery. No holograms, deep shine, perfect.
The problem was the fish eyes and dust nibs that they couldn't cut and polish out which led to body work which let to another detail job before they handed it back to me where it almost seems like the worker was purposely doing a terrible job, or over worked and just didn't care.
The exterior paint has holograms all over, especially the front clip where most of the rework occurred. Then the interior they either spilled something on or used the wrong chemicals to clean the piano black material and noticeably etched/dulled the finish. Also noticed shiny spots here and there on the seats where it was like they sprayed say... armor-all on the back headrest, wiped it, and left the rest of the seat alone, leaving oily places here and there.
