Under sunny skies, New Canaan welcomed about 3,000 auto enthusiasts to the center of town Sunday to check out hundreds of unique and exceptional cars for Caffeine & Carburetors, lining Pine and Elm streets.

"It went very well, very smoothly," Doug Zumbach, the event's founder, said Monday. "We had some spectacular new cars, some very rare Ferraris, Porches. It was just a very nice show."

The gathering may have featured the largest number of vehicles on display to date -- 740, according to an unofficial count. Zumbach, who owns Zumbach's Gourmet Coffee at 77 Pine St., said the "perfect" weather and the four-month break from New Canaan contributed to the success of the show.

Sunday's Caffeine & Carburetors was the first held in town since May 4. June's event took place at Lime Rock Park after organizers and town officials agreed to reduce the frequency of the car show downtown largely because of traffic and parking concerns. The downtown showcase was originally scheduled to take place six times this year, as it did between 2009 and 2013.

The number of vehicles and participants at Caffeine & Carburetors has been growing larger every year. The May 4 event attracted nearly 4,000 people and more than 400 cars.

On Sunday, drivers came from as far as upstate New York or Maine, Zumbach said, but no issues were reported as 25 volunteers, 10 of them from the New Canaan Community Emergency Response Team, as well as five police officers helped control crowds and traffic in the area.

"Everyone had a good time," he said. "By 12:30 (p.m.), you wouldn't event know there was an event."

About 40 shopping bags filled with donations to the New Canaan Food Pantry were collected during the event.

Two future sessions, Oct. 5 and Nov. 2, are on hold. Zumbach said he would ask the Parks and Recreation Commission at its meeting Wednesday night to have the show at Waveny Park at either one of those dates.
