I have noticed a lot of people selling the new GT500s with low mileage as well, I feel maybe that's due to the people that bought them bought them because they were the newest flavor of the month and they're onto whatever is next. The 13/14 GT500s just the like the 03/04 Cobras will gone down in muscle car history as the kings of there time. At the end of the day I find lots of thing I like about them both. I bought my first 13 GT500 brand new in 2013 and man it was one of the best moments of my life and I've had 2 more after that. I guess maybe that's why I was looking at buying the new 22 GT500. I was looking for that feeling again. But maybe it wouldn't be the same, IDK. Ultimately I would like to own them both, and maybe one day that will happen....or I'll buy a 13/14 Super Snake lol.They can be compared.Its all about what a person likes or does not like and what that car means to them.The 2020 to me looks like ricer shit with that black bumper.On the other hand,it is a TRACK KING!!It beats the Crapmaro zl1,1le on the track.As for ME,the 13-14 will always look better than the new one,and i prefer the 6 speed over the DCT which does everything for a person.If i won a new one,i would trade it in instantly for a 13-14 GT500 widebody supersnake.When you to cargurus they have 140 used gt500s on there with maybe two being not used.There are alot of people on different Mustang forums that have sold the new gt500 and gotten a GT350 R or went back to a 13-13 GT500.There are 60 13-14 GT500s on there as of now.
