I’m in the same boat as you, but with a Dodge. I thought about a 6 speed manual Challenger RT but I decided on a 2014 Charger RT with an auto 5 speed.I just bought a 2019 Mustang GT, with..... an automatic transmission. It does have paddle shifters that I use, but there is no way I'm going with a manual. Automatic has 10 gears and can outshift a manual in a race, so I'm perfectly fine with it. Not only that it makes a better daily driver. I can put it into S mode for pure paddle shifting, or into sport mode where it sticks with a gear higher into the rpm band.
