With my 92 300SE I'm still suffering and it only has 49K on it. That S class didn't get it close until about '95 and then still not all the bugs out. With over 300 new patents on the 2000 S I think I would wait a couple of years or find a used exec car with a 100,000 mile full warranty! Good luck. With a video at close to $8k imagine what just one claim would return on an extended warranty cost...you would be way ahead!
