Just simply pick 2 or more pairs of cars and test will be fine. Then can say which model is faster but not who is faster. But I think if got chance to test with the fastest one is sort of lucky and being given face too. Maybe a joint TT will be ok. I don't mind to sponsor a TT session. Hopefully mid april will have time to arrange it else looking at Jun 2010. I bet both cars will have less than 4 meters different in 0-400. More than 1/2 a lamp post can consider win and more than 3/4 tiang is consider smoked

But must secretly do it la. I worry someone who has 1000hp supra standing aside laughing or yawning
