Mine with quite a few mods gets 12-13. When it was almost new with a 289 with a 2 barrel and single exhaust, it got 16. If economy is important, don't get an oldie. If outright speed is important, you can do better with a newer one. The only reason to get an old Mustang is just because you love them. I doubt anyone will disagree with me here.
