I believe he said it was an e46 M3. Which is no slouch of a car, and can take out soem lower level Porsches andmaybe a regular Corvette, but it's not exactly a supercar.
I thought he said it was a 99' M3, the e46 version came out in 2000.
Just double checked with my BMW-guru friend, the e46 M3s came out in 2001. So yeah, a '99 would be a e36. My bad.
