Anyone with any experience with this Company or thoughts on buying a warranty for a used car? Just bought an older SUV with high mileage and would like to keep it for some time. Car is in great shape, one owner, mostly highway miles. Covers engine, transmission/transfer case, water pump and seals and gaskets. Person we bought the car from is suggesting this company. They will sell a 5 year 100k warranty for just over $1,000. One of the stipulations they have is that you must change your oil every 4k miles. If not, they can use that to deny you coverage on a claim. Thoughts?
