It's a crap shoot
I own an automotive repair shop. I buy extended warranties even on vehicles that I purchase. Because even at wholesale, having to purchase a new engine would be pretty hurtful. Worst case scenario I know but I see what repair costs can be like. So I also purchase extended warranties on major appliances for the same reason. Worst case can be a real bite to the budget so I factor in the warranty before the purchase so I get what I want and the protection that I want as well.
