I wouldn’t spend that much for extended warranty  my understanding is the 650 and 850s are reliable  I would never keep a sled beyond 6000 miles / 10,000 kms anyway myself  $5000 seems like quite a lot for extra protection 

My buddy from the city put my wife's venture.on it's side twice with her on the back. Lol. He has one of our bike helmets on.

Got outfor a little ride. Checking local trail for downed trees.

$2k I would buy it.     $5K I would roll the dice.     

I was just thinking along the same lines from an automotive side - spin the dice and if you are worried about it, do a rebuild when you hit the mark.  surprised none of the poo guys have commented on the longevity of the motor though.  I know my 2 stroke cats I’d never consider it - only issue I’d have in the back of my mind is possible issue with the display, not sure it has the good or inexpensive one, and again, how often do they fail, does warranty cover that even and what is a replacement.
