I was looking for a v6 version of the 2013/14 Mustang convertible when I came across a killer deal on a 2013 5.0.
i am sure I would have been happy with the v6 but after having a v8 with the required loud exhaust I don’t think I could go back.
I don’t get into drag racing, I was coming from a MINI Cooper S and Miata, the Mustang still feels huge but it is fun to autocross.
to the OP - I would go with the 4.6 unless you can squeeze into a 2010 GT.
