I dont see what is wrong with the car club concept. Granted I am in one so I guess thats why...LOL
But to me I have more fun at shows when I am in a team, We do things togther, Show togther, The friendships and bonds that are made cant be explained. To me clubs/Teams help build the show scene. The show scene is much different now then the days we had many clubs around the area, things have died way down. The 
rivalry between teams is always fun, it helps people within the teams strive to build bigger and better cars to compete with eachother and other teams. 
If you are not in one I and dont see why they are around, you wouldnt get it I guess.  
I have been on both sides of the game though, I started and ran a team for 3.5 years and then went solo for 1 season and now am in Elite and having a blast. Some of my best time have been with a teams.
