I'm looking at an 05 Titan SE 4x4 at a local dealer that has about 68k miles on it. This is obviously outside of factory warranty, anything I should be concerned with about future reliability on an 05 Titan? The same dealer also has an 07 Chevy Avalanche LTZ that looks nice (thoughts?). I need to truck for towing and normal usage. I drive 12k miles per year and was wondering what sort of milage I can expect on the Titan when traveling 75 mph down I35.
