Mustang clubs on Oahu don't appear to really be overly acceptive of new comers, Aloha
www.alohamustang.com/ has over 500 members they say, most members I've met are nice. Aloha Shelby and Mustang club guys are usually at Wendy's parking lot in Kapolei every Saturday night... download the member application on line and bring the $50 bucks annual fee to one of the car shows or mail it to them to join.
HPM
www.hawaiiperformancemustangs.com/ seems like a smaller group, younger, more fun crowd but not much appears to be organized regularly, I haven't actually met up with anyone from HPM only seen stickers on mustangs on H1. I joined the online forum and donated $75 bucks online to HPM (Hawaii Performance Mustangs ) but never heard anything back from them either, their web site says to join you have to show up to one of their organized events... HPM runs on donation only...
Kalaeloa Raceway
www.kalaeloaracewaypark.com/ in the Kapolei area has shows and events too featuring both clubs and just cool people with hot cars...
Beware though - (had my application and check for Aloha with me but ripped it up now) watch out for the haters at Wendy's parking lot... It is an unofficial car sit and shine where all the island vintage rods and newer American Muscle: Dodge, Chevy, and Ford park and show off their cars, was really fun the first night tons of super cool cars and project cars. Went 3 Saturdays, then got threatened on the 4th Saturday and screamed at by some jerk because I revved up my engine the previous Saturday when I left, no just talking and being civil - upset this guy once and be harasses forever. The guy and his kid write license plates down and call police, unless you ask why he is writing your info then he yelled that I was exhibitioning and says he is going to call police, once again, hates new comers evidently.. I could definitely show him what exhibitionism really is... LOL
Shucks, I even went to Kmart after that and got harassed by this jerk - parked at the other end of the lot! Nuff Said.
Lets meet up and cruise I just want to have fun!
We did circle island and Kapolei to Yokohama Beach last weekend (check out the album if you like). Anytime - I would love to get a chain of mustangs together to cruise rather than sit and have people lean all over my car... Im on westside Oahu. You can message me on Makakilo Mustangs if you are serious about weekend cruises.
