The Car Club Council of Greater San Diego calls its automobile attraction “the greasiest show on turf.”  So, they’ll use a new venue at Liberty Station to make the point with hundreds of cars on display on Sunday, Sept. 11.  This signature fundraising event for the San Diego Automotive Museum has been a tradition for a number of years at Balboa Park. But it has outgrown the park and Liberty Station’s “turf” was chosen to replace it.  The free show runs from 9 a.m. to 2 p.m. The car registration fee is $25. In conjunction with the significance of the date, a memorial ceremony for those who lost their lives in the attacks of Sept. 11 will be featured at 10:30 a.m. There will be the presentation of colors by several law enforcement agencies as part of the program.  “Looking at our early entries, we could have over 300 cars of all marques,” said chairman Geoff  Ferber.  “The show is expected to draw a huge variety of vintage and classic cars, hot rods and racers and customs that are sure to please.  Lowriders, motorcycles and scooters have been invited to participate this year.  “We’re going with an open class,” he said. Anything that drives and moves. With this new venue, we should match what we had last year. We’re also reaching out to the wooden boat class runabouts as an added attraction.” Ferber said this is the only show where all the county car clubs participate and there are 100 of them altogether. As an open-class show there will be 25 top picks plus three special trophies.    For fans, of the classic 1950s and 1960s vintage, this show offers the best of these lovingly restored machines.  Personal favorites might be the 1955-1957 Chevys or the 1950s-era Ford Thunderbirds. Whatever their favorites, visitors will see that classic car shows offer a nice blend of nostalgia — a time when collectors say cars were cars.
