I have an old muscle car and you seem to be forgetting that in order for them to be fast many had gears based for drag racing and at best a 4 speed manual transmission. They could launch, and had a great 60', but no top end. Most modern cars and SUV's would have no problem catching a muscle car after a quarter mile...
Acceleration is where the muscle car will likely get a modern commuter car, but the modern car is going to outrun the muscle car in a long run. Modern cars have more gears, highway gearing and a more stable platform at higher speeds. So stop talking out of your ass, you're embarrassing yourself...
Given the option I'll always take a muscle car over a soulless like-a-like modern car. But I'm not delusional enough to think I going to out run a 6 speed 250hp SUV on a long run, in my 3 speed 4.10 geared 395hp muscle car, just because I have more HP.
