I have a 2009 Challenger R/T, 6 speed manual. It is a great car, and gets 28 mpg cruising at 75mph on the highway. My wife has had a Charger R/T since 2012, given to Daughter in 2018 when we got a new Charger R/T to replace it, they both have got 30+ mpg cruising at 75 mph on trips. They are great road cars and have acceptable handling and acceleration even with a 5.7 and an automatic. All that said, the car I will keep to the very end is the 1966 Formula S Barracuda, with a 273, and with a 4 speed and a Hurst shifter.
