Your GT Convertible C/S looks really nice....the "15" doesn't come close to yours styling wise; my humble opinion! Additionally, even though the interior of the "15" looks great, it's not enough improvement over my "14" to create enough desire for me to trade up.
I purchased mine as a CPO and the previous owner removed the GT/CS stripe and attached the "5.0" emblems. That year the stripe went across the middle of the car. Subsequent years have the GT/CS stripe down by the rocker panel.
I'm debating if I want to order the stripe from a later model GT/CS that so I can keep the "5.0" emblem.
As much as I like the new Mustang, I do like my GT/CS. It stands out a bit more.
It's also truly a summer car. I originally had a 2006 V6 convertible that I traded in along with my previous car in order to get my DD which is a 2012 CTS-V coupe. As much as I love my V, I missed having a convertible and a Mustang.
Picked this one up for the summer days
