 How is it that I need a new engine?  It's 4 years old, I bought it brand new and it only has 75,000 miles.  I am anal about taking my car in for service and have never missed one.  I had an 85 Sentra in high school and that's the reason I bought a Sentra again.  They obviously don't build them like they used to.  I will never buy a Nissan again.  Nissan, you're dead to me now.
