 I bought my 2007 Maxima brand new.  I have had more high dollar repair/replacements than anyone I know with any kind of car.  I have replaced: the catalytic converter, power steering pump, power steering hoses, motor mounts and the battery at least every two years to name a few off the top of my head.  Oh, wait, both the passenger and driver's side sun visors gave out and the passenger side power side view mirror.  Oh, and the hydraulic things that keep the trunk from slamming down.  I have service done at the local dealer (Casa), so I assume I am either getting the service needed or I'm getting hosed.   Either way, I will never own another Nissan.
