I want to chime in on this. I produced the 2010 car show in Nashville and was associate director of the ZCCA in 2009 and 2010. I have never been to the MSA event. The ZCCA is a huge car club involving scores of Z-car owners and enthusiasts all over the world. The annual convention is several days of activities involving Z-cars and related Datsun / Nissan cars. It encompasses several activities with cars; it is not just a one-afternoon car show. There are rally and racing events, motor tours, and social events for the participants to get to know each other and share experiences. One of the most important things is for the host club to show off their special city and region and for the participants to experience something new, travel...with their cars! That is why the convention is in a different place every year and that is why there is simply no comparison to other outstanding Z-car events. For instance: If not for the 2004 convention in Long Beach I wouldn't have met Mr. Katayama, Len Welch, Katsuhiko Endo, John Morton, Brian Long, and many, many new friends including Lai Mee from Hooter's. I wouldn't have paid extra for a heavy suitcase full of car parts! If not for the 2005 convention in Rochester, I wouldn't have driven Watkins Glen and paid extra for that heavy suitcase. If not for the 2006 convention, I wouldn't have driven the new 350Z r-tune. I wouldn't have trophied the hardest rally I have ever run. And I had two suitcases to ship home from Dallas. Oh! And then there was that evening with the Japanese guys touring the gentlemen's clubs! If not for the 2008 convention in Cleveland, I wouldn't have driven Lime Rock, experienced the Rock and Roll Hall of Fame, or sampled Nissan's new GT-R. San Antonio in 2009 was just over the top. I met Steve Millen, drove a great rally through hill country, saw the Alamo, found a really great junk yard, and I gotta mention Amanda the Z1 Motorsports model. Whew! The annual convention is so much more than a car show. Go to San Diego - have fun - give my best to the Hooter's girls - enjoy clowning around with all your Z-car friends.
