OT
I don't care to prove my point, but since you have plenty of 'Informative' flag, I feel need to clarify for people that may think this is import: you have no clue what you're talking about re people that buy car with intention to go to a track.
Firstly, most club events forbid lap timing. Events organized by clubs is where the mass market is. Exclusive events (for profit, by dealers, or sponsors like UnpluggedPerformance) with no insurance and plenty of track time, they are irrelevant, too few people to account for anything. Secondly, track rats participate in club events for the joy of driving and adrenaline, not for competition, and they maximize every minute they're allowed on the track, so no one in their right mind would leave after 5 laps in a session. Etc, etc...
So your whole notion of 'I can do few laps as quick as BMW M3' does not represent mindset of a person that would buy car for the track. This is my final post on the subject.
