I'll just through my hat into the ring here aswell. Now I have been to a couple of Honda meets up in Scotland and there was one where I made a few phone calls and got 4 NSX's to turn up.
But I don't think that this site is the best place to advertise such meets unless there is a section devoted to "other car/ Japanese car meets"
It has already been said that there are a lot of sites on the web for other car enthusiasts to arrange meets. It is true that youdo get the chav element turning up, but they are not all like that.
