I am looking at a 05 titan with 70,000 on it. My friend owns the shop, and a different friend works at the dealership where the warranty work is being done. Long story short is they found a clogged up bank 1 cat, and now they are replacing the motor for free due to it sucking up particles from the cat. I know that this has happened in the past, but do I still buy it now, or is this a blessing. A free motor and cats. Any feedback would be awesome.
