Chrysler Turbine car promos

Back in the mid to late 60s I was with my family at a obedience dog show in the San Fernando Valley east of Los Angles. Also at the same park there was a car show. All of a sudden there was a winding up sound of a turbine. A mass of guys, including my dad with me in tow all hurried toward the sound. Turns out one of the cars at the show was a turbine powered car and it was the highlight of the show to see and hear it. Not sure if it was the one referenced above but it was cool and a fond memory.
