The average medium size sedan today can easily be equipped to outrun and outhandle anything but the most awesome of '50s and '60s iron.
I used to own a 1998 Nissan Maxima that had only a couple of mild suspension mods, plus bigger tires than stock.
A neighbor of mine had a '66 Vette - we agreed to see which was faster over a point-to-point country road run. He beat me by less than 15 seconds out of ten minutes.
Recently test drove a Hyundai Genesis Coupe. 0-60 in under seven seconds, handles like a go-cart, and priced in the mid $20s.
Mind you, I'd still love to drive a tri-power GTO or a Hemi Roadrunner (or especially (drool) a Cobra Daytona) if I had the chance....but the idea that today's cars are performance impaired is, I think, a myth.

They can’t climb mountains real well. That I know without question, especially when loaded for trips.
