I’m looking for the average price and MPG for the following cars:

1951 Ford
1955,1956, and 1957 Chevrolet
1957 Studebaker
1959 Ford
1959 Cadillac

I live in Florida, where would be a good place that still sells classic cars? I saw a commercial that says they play music from the 1950s and sell classics but I forgot the day and place. Anyone know of it?
