This is the dashcam footage from Daniel Sheikhan's $170,000 Mercedes S63 AMG after he dropped it off at the dealer for a service appointment.  After watching the footage he discovers the technicians spent a total of 11 minutes with the car on a lift before taking it out to get Frosties at Wendy's.  Then they run the car through the wash and drop it back off, charging him $700 for transmission service, which is apparently the technical term for joyriding to Wendy's for Frosties.  No word what they do for a lube job. 

Keep going for the video. 

Thanks to SD, who's not surprised.
