What new gen Challenger is best and Why?

Ok since you asked. I started with a 2010 5.7 with a manual transmission. Nice car no problems. Then went with a 2014 5.7 with the auto transmission. I know just a couple of months ago bought a 2017 3.6 sxt plus I think it has everything but a sunroof. I didn't think I would like the newer style, but now that I own it I love it. BTW my first two R/T had track packages. I wasn't sure if the 6 would be enough, but with that new 8 speed transmission it's awesome. I really could afford more of a car. I just really didn't want it. If you get an older one get one with the STP. Good luck I love em.
