Okay, here's what I mean.

Here is my win with the EXIV 200GT (very close, would be difficult to repeat)...

Here is my win with the Lancer EvoIV GSR (tuned with only TS3, same as the AI, AFAICT)
A fairly easy win, which I'm sure I could repeat...

Interestingly enough, the EXIV 200GT beat an "AI" version of the same car. Similarly with the Lancer EvoIV GSR. Note that my Lancer beat the AI Lancer by over two more minutes than my EXIV 200GT beat the AI EXIV 200GT. Let alone the fact that the AI EXIV200GT normally beats the AI Lancer.
The AI results might lead one to conclude that the EXIV 200GT is an easier car than the Lancer Evo IV (at least with the AI TS3 only mods) with which to win the GV300, but that is certainly not the case.
