Aloha Birdofprey,
There are several British car owners here on Oahu. The British Car Club of Hawaii is a multi marque club, but MGs and Triumphs and most numerous. We hold monthly meetings on the second Tuesday of the month at the Elephant & Castle Pub on Kaahumanu St (Diamondhead side) in Aiea. The meetings usually start about 7 PM. We recently had a road rally around Hawaii Kai and Waimanalo. We also hold monthly tech session at members garages. Hope to see you at a meeting. I'm sure you could work with the club and get a drive organized, after all driving the cars is the best part of owning them.
Safety Fast,
Dave
