The new cars, while much safer and much easier to drive and enjoy than the old muscle cars, they aren't exactly going to blow the old ones off the road, my 440 powered 69 charger can easily challenge the newer R/T and SRT8's in a straight line, even with skinny tires, borderline brakes, and sloppy steering, they still handled pretty darn well compared to other cars of the era. I got my new challenger because i needed a safe and nice looking car to drive daily, something I just can't do with the 69 charger, as it gets a whopping 6mpg in the city, and 12 to 14mpg on the highway if driven sedately, and if something breaks, it is hard to find the parts and they aren't cheap to replace. I'd rather keep the charger for cruising around and showing off at shows, and doing the occasional burnout to relive yesteryear, but I still want to drive a newer car daily so I don't get overly paranoid parking at lowes or Kmart, and I appreciate getting 22-25mpg on the highway.
However, when the challenger crosses 100k miles, I will very likely sell it, whereas the charger will never be sold, I've owned the charger since 1978, it was my first car, and it will be my last car, I don't care that its increased in value from 800 dollars to over 35000 today, I've torn it down piece by piece, and reassembled almost every part of the car, I know it intimitely, and nothing, repeat nothing can beat the sound of a 440 under full throttle.
