I took my sc'd e34 540/6 and my buddy Josh took his M20 525i and his turbo 240sx out to a track day at Talladega Grand Prix TGPR roadcourse. There were some e39 M5's, some M3's (e36 supercharged, and a e90, e92, e93, whatever) as well as a Z3 coupe, and a turbo MR2.

the 540i spun off track as brakes are required for cornering(?)
the 525i went offtrack to chase some cows
the 240sx blew a testicle out the side of the block
the SC M3 sucked was just broke
the black M5 dominated the slide-magic
the Z3 got smashed (wheels suspension=demolished)
the MR2 kept overheating
