Donovan Auto and Truck Center has been family-owned and operated for three generations. Our founder, Les Donovan, opened our ... dealership back in September of 1977. He set a high standard of excellence, making our customers the top priority. The environment at Donovan Auto is relaxed, professional, honest and stress-free.
