How does that play out for you? Since your mods are doing pretty much nothing in terms of actual power, it means that if he can drive and he has his top up(aerodynamics make a huge difference), he'll beat you pretty badly. And don't race an ES350, because a decent driver in one would beat you, too. That race might be closer, but I doubt you want to risk having to admit you lost to an ES350.
It also means that the race between a GS350 and a M3 convertible would be closer, but a good driver would out-edge the GS 350.
