Take your car and run them on a good 1/4mi track stock for stock and see what happens. The M3 is fully capable of demolishing a 370z when both are stock...but that's not to say your boss is fully capable of taking the M3 to that level
I've seen Vettes run 14's fairly regularly...and it's not the car that's the problem in those cases. Heck back in '02 I had a friend with an Integra Type R that was turbocharged and put down 340hp to the wheels. He couldn't get out of the 14's on street tires, so he thought it was a traction issue. He bought drag radials and only managed some 13.7's and one lone 13.4. I asked to drive it and clicked off a 12.7 on street tires and 12.4 on drag radials (and I'm not the best driver in the world). We got our shop driver to drive it once on street tires and he clicked off a 12.4....on street tires (we never got to see what he could do on drag radials).
Long story short...you never know. Run em and see what happens.
