My former Ford Dealership in Texas City, Texas (Gene Hamon Ford) now Cook Ford does all my service on my GT. Larry Leonhardt is the certified mechanic there and does all my work. Larry's father was our mechanic in the 60's with racing Cobras and a Mustang GT-350R (108). Larry has been at the Dealership some 22 years and is the only one who has ever touched my GT. Tomy Hamon
