Ten Of The Best would easily show all the kind of things your talking about if the Supercars bothered to show up.
In fact usually at least a few do, and get their arses handed to them, not that superising considering almost all weigh 1500kg+, many over 1700kg.
Cool to watch, and suprising for your average person no doubt, but the top modded cars in the UK will destroy the best 100% standard Supercars in straight line acceleration, and a good few will around a track too, all things equal.
Thats modified cars for you.
