1993 was the last year for the 4 cylinder Mustang, it was just to slow for the image..
1974 was the first 4 cylinder in the Mustang II..
the four was only available in the 2nd and 3rd generation Mustangs,at first a 2L and then the 2.3L
I would recommend the v6 automatic, it's what Hertz and Avis rents out to the public..
