Not sure which 1999 Ford Mustang Floor Mats & Liners are right for you? We have over 202 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. CEASAR G from Corona, CA said, "The mats look great in my mustang. The fit is not as I expected. I had hoped for more coverage. The diver-side rear passenger side mat didn't fit well because the cut out for the seat-belt harness anchor was over exagerated. Hexomat customer service was outstanding and worked with me to get a better fit, and they sent me a new mat that fit better. I gave them an excellent rating on all counts except pricing. I have Hexomats on my 2005 Mustang and they fit perfect."
