Back story on the dealership.
About 1951, the dealership moved to the western edge of downtown. Charles Nash (previous owner - passed away in 2011 at age 87) once owned land at all four corners of Fifth Street and Lamar Boulevard that included the dealership, a used car lot and a body shop.
The dealership moved to South Austin in 1998, to make way for Whole Foods Market's new headquarters and flagship store.
I am guessing that unless they moved their paperwork that they tossed it away but I have still hoping. Also there are several photos of the dealership in the early years including a video in the early 60's.
Trust me Ive done my homework. Just looking for someone local that may know or want to help a brotha out.
