Will,
A good detailer charges 150-200. Just as a note, most good ones make about 40-60bucks an hour.
If you are looking for a quality job let me know. I get the TT detailed by a guy that does F cars and Bentleys and Astons only. He spends about 3-4 hours on the car, and charges me $160, but I am a regular. He does the whole clay/polish/detail interior/exterior.
Great job. You know where to find me, if you are looking for help.
