I found that all the extended warranties offered by third parties were worthless, they all had a long list of exclusions, stringent maintenance requirements and many had a pre warranty mechanical check out that often you had to pay for. They are expensive and cover very little.
Now I did research manufacturer offered extended warranties some manufacturers will offer what is really a third party warranty and some will offer an actual manufacturer backed extended warranty.
I did purchase the extended manufacture warranty for a new vehicle that I ended up never using. This was a Toyota warranty offered by Toyota and only available if the vehicle was under the original manufacturer warranty. I did not purchase through my dealer which wanted $3,500 I went to another Toyota dealer on the internet and got it for $540 (see how much markup there is). The manufacturer covered everything except wear and tear cosmetic items, fluids, belts, brake pads etc, but all mechanical items. It also offered towing reimbursement, a vacation reimbursement, and rental car… So at the time I believed it to be a good deal. We never had to use it, so if I had to do it over again I would not purchase this in the future.
In order for a warranty company ( for any warranty) to operate and stay in business, over the long haul on average they must take in more money than they pay out…
My advice take what you will pay on an extended warranty and put it into a savings account for a rainy day.
