Comparison of two Mercedes in which the main question is – the brand new Mercedes-AMG C63 or the older brother?

This American tandem is doing a show showing cheaper cars that can match the more expensive ones, so they have now tested the 2020 Mercedes C63 S Coupe and the 2013 C63 AMG Coupe. When we look at that V8 engine we will see pure power, around 480 hp and 600 Nm of maximum torque, versus 503 hp and 700 Nm of torque.
The difference in price is considerable, the version from 2020 costs around 80,000 dollars, while the version from 2013 costs around 30,000 dollars. What car would you buy?
