Thanks everyone for this thread, I'm at 49,800 miles and was looking for an extended warranty.
I found a podcast called "EV-Resource"; episode 109 is a hour long interview with Brent and Milad from X-Care
I went to the X-Care website and ran a few what-if scenarios on their coverage calculator. One of many important facts is that the cost is not linear with vehicle mileage, it goes up in 10K mile increments, Thus if my car was at any mileage between 40,001 and 49,999 miles, a 4 year 50K mile policy was about $400 cheaper than if I let my car hit 50,001 miles!
So, after watching the podcast, and talking to them on the phone, for the first time in my life, I nave bought an extended vehicle warranty.
