Let Down Some!
 I paid dearly for this car as my retirement ride and never planned to baby it and never did.  Just put gas in it and used Amsoil exclusively which I recommend highly.  Once a year oil and filter changes. At 60K miles I started having some issues with the fuel air controls and computer module that were very costly to me.  Being retired I had a hard time forking over 1200 dollars for a new O2 sensor manifold that sits atop the V6 engine.  Now I have a computer error P 1135 and I am waiting for an estimate on that damage.  Not happy one iota with the last year of service in 2009.  I had expected better longevity.  I believe the air fuel system is the weakest link on this automobile.
