Jeff built both of our racing 240Zs, and currently provides outside maintenance, repair and improvement services. They are extraordinary cars, both mechanically and cosmetically, with considerable racing success, and I say this as a man who owns 16 race cars, and has raced on and off for over 40 years. The Zs have been fast, safe, well-handling and reliable cars, and are a blast to drive. Jeff has my highest recommendation – and much appreciation – for anything Z or Datsun related.
