High end electronics. As an electronics installer and electrical technician I have occasion to call the manufacturers of high end electronics to get troubleshooting help. I deal mostly with technical support, but I've had to talk to some customer service reps as well. Apparently, paying $15k for a computer and touch-screen all in one device (MFD) comes with a certain level of lifetime support. One time a customer's brand new 22" Garmin MFDs bricked during the first update. Garmin took a $30k hold on his credit card, send him brand new ones express, and had him send the broken ones to them to get the hold removed. Unfortunately the MFDs bricking sucked, but everything else about the experience involving the company seemed extremely straight forward and convenient. (For someone who can afford a random $30k hold on card.) Luxury goods have the best customer service.
