You would probably have trouble in most smaller cars. However, there are ways to "extend" the seat tracks or even move them back to give you more leg room. I think there are kits for this but not sure if the 65's are included here. The 65 Mustang is a very nice car but I would think you might not have a lot to chose from in Slovenia. And, parts would be a problem, I think, too. Good luck, my friend.
