After Frank E. Rhodes was renamed LaBonte Rambler, LaBonte sold and serviced Studebakers until the 1965 model year, according to the South King County Telephone Directory from 1964. The building looks very similar to one in Grants Pass, Oregon :
It was the oldest dealer because Laurent Belcourt sold Studebakers from 1940-1956, then DeSoto from 1956-1961, and then Studebaker again from 1962-1966
