My husband absolutely loves Ford Mustangs, especially because they are American made.
My sister's first car when she was young was a mustang
They were originally made as two seaters in 1962, but eventually became four seaters. Which kind did your sister have?
I believe she had a 4 seater.  I think it was a 1968
That is what my husband had. They seem to have stood the test of time, since they are the most popular Ford since the Model A.
