Ha! I did a "drive a NASCAR car" event yesterday, and that's a very different experience than an M3 on the track. You know how your M is precise, and balanced, and smoothly puts its power down?
Now imagine being belted into a freakin' hot, loud, aluminium sandwich, with terrible visibility and handling like a dump truck
Loose steering, pulled to the left (go figure... ), barely perceptible brakes - basically like driving a water buffalo with rocket engines.
But oh what an engine - running slicks, coming out of corners at about 60, when you floor it the back tires immediately light up and the rear end starts hopping around. And that glorious monster engine sound
It was great, if you're looking for a change of pace I thoroughly recommend it!
