From Infineon Raceway's website: 

"Tiburon's Gary Lucas will pilot the oldest entry in the field with his 1915 Ford Model T.  Lucas, who has been a firefighter in San Rafael for 30 years, has owned the vintage car for more than 20 years. Lucas has also competed several times in The Great Race, a 14-day, cross-country trek, in his Model T.  Lucas' father, who owns a 1922 Ford Speedster, is also passionate about vintage cars and serves as his son's riding mechanic, including manually pumping oil and gas throughout the race."
