[Source] Doctor Hudson: Dr. of Internal Combustion (also later known as the Hudson Hornet Racing Museum) is a location in Radiator Springs in the movie, Cars. Doc Hudson worked as a doctor there, "fixing" the cars of the town. When Sally broke down in Radiator Springs, she was fixed here by Doc. On the side of the building is a garage, where Doc stores his old racing memorabilia. It closed down in Cars 2 and was made into a museum about Hudson after his the death sometime after Cars.
