Don't accept one without testing it thoroughly first - even a brand new one. Bad clutch judder in first and reverse especially on hills (evident at 100 miles then getting progressively worse). Gets worse as clutch warms. Infiniti garage says its the same on all new 06MTs, if I had known this, I would not have bought the car. The other two I drove did not make a banging noise when I release the clutch. Excellent car spoiled by poor customer support - denial by mechanics and a poor clutch design or faulty components.
