First, the motor runs great at 140K. The trans has started making noise. Undrivable right now. When I replaced one of the xenon headlamps, I had to pick my jaw up off the floor, we're not talking about the whole assembly, just the bulb itself. At the Nissan dealership in Victorville, CA $258.00 for the bulb!! Can you believe it? I went on line and found the cheapest to be $159.00 My suggestion for someone who may not want to pay that much is when the xenon goes out, run your brights instead of replace. Bright bulbs cost $8. Oh, the spark plugs are internal. Tune up costs $418.00 to replace 6 spark plugs.
