Any/all of the commercials heavily touting such plans are likely NOT a good deal for consumers. Auto Warranties... I checked into one currently heavily advertised. For 5 years the insurance premium for my 2 cars would be $22,000. I could replace a LOT of parts for that, if any. Reverse Mortgatge... basically you're borrowing your own money... your home equity, at interest, but you have the convenience of not having to make monthly payments. The "balance" is settled upon the last occupant leaving the home. Interest rates run 5-6%/yr., compounding... rather high in this world of 0% earnings on savings... PLUS usually a "hefty up-front fee" to initiate the program. As a general rule... if something is heavily promoted on TV, there must be an OUTSIZED PROFIT for the promoter... even after the TV advertising costs... all at the buyer's expense. (Frankly it annoys me that Tom Selleck tries to come across as your "favorite, trusted uncle giving you advice", while he shills for reverse mortgages.) Opposite Example... You have monthly income from some sort of settlement, and you want to "cash that in" for a lump sum of money today. I looked into one where they paid "20% up-front". That is... for the sum of your future monthly/annual payouts being $100,000, they'd pay you "$20,000 today". How badly do you need the "up-front money, right now"? Bottom Line... Caveat Emptor... look before you leap.
The auto one you quote is even worse than the dealer version, by a lot. I admit I did get one after some haggling on our Honda van. I lucked out, I guess, in that it ended up needed a couple of pistons replaced because the computer kept crapping out and oil was burning off like mad. The dealer kept flashing the computer, and it kept failing. I forget what the bill would have been without the insurance, but it covered the cost and quite a bit more.
