Does anyone know a good after market extended warranty company. I have herd so mant bad things dealing with them

What ever you do, do not get an extended warranty that is not offered by the manufacture. I am a technician and these after market warranty companies send these adjusters to look at the vehicle for any reason to deny the claim. A customer recently brought over his truck because the radiator was leaking. The adjuster came by and said that they would not honor the claim because he had changed the tires and put a lift kit. I am not making this up. So I asked him, what does the lift kit and tires have to do with the engine cooling system, he could not answer me. The bottom line, DO NOT BY AN EXTENDED WARRANTY unless offered by the manufacturer.
