I know Sicks car will trap at least 125mph. It did over 123mph with me in it, and not even running perfectly. I doubt stock M5s will touch 125mph on a level run. But its simple enough to grab a Vbox, find a level road and see what the 1/4 traps are and the 60-130 times are on the same run.
Terry's car was doing back to back 130mph runs on the same level test area, and Erics car should be right around 130mph too. 10 second capable cars. Just look at how well the E63 did against this M5, the GT, and Gallardo, etc.
