About The 1988 Mustang
The 1988 Mustang had a lot to live up to after such a successful model year as 1987! Ford realized this and as a result made as few changes and revisions as possible for the new model year. Not fixing something that isn’t broken was a good motto for Ford to follow during this time period and it worked for them, too. There was an increase in production of GTs in 1988 by 20,929 units over 1987. The total amount of 1988 GTs produced was 68,468. The GT was a super popular car!
