There are a few clubs I am aware of: Saddleback Valley Mustangs Orange County Mustang Club (OCMC) Links to find clubs: http://www.tcmustangclub.org/Mustang_Club_Links.htm
Ventura County. Not close to you but we have a good web site and have a lot of fun. http://stangfreak.com/content/
yeah apparently i cant join saddleback mustang club because i do not meet the age requirement. how lame is that?
im part of OCMC, but let me tell you, depending on your age, it might be boring for you, im 34 and 80% of the club is about 45 year old+. The only thing i get from it is info on upcomming shows. If you want a couple of forums to check out,socalhorsepower.com and lamustangclub.com. I post regulary on both and meet up with both everyonce in a while. A few people about 30-40 cars)started meeting up at Frisco's diner on Wednesdays in City of Industry.
That is surprising. I would have thought they would take anyone interested in Mustangs regardless of age. I know I joined my first Mustang club when I was 16. Must be some sort of legal thing...
