So, the datsun has definately spoiled me. I just changed the plugs, cap, rotor and air filter on my new 850 turbo wagon. Can't believe all the crap you have to remove to to get to the cap. Then its held on with three screws. The rotor is held on with three allen head screws. I had to remove the air box, a turbo intercooler pipe, and other crap. Pain!!!
Just thought I would share. Can't wait to get back to the Z.
