Dan, I get an occasional newsletter from Irvine...I think I probably signed up for it on the SPF website.
At any rate, here's the link to the reunion info.
Superformance Owners Association - SUPERFEST 2013
Still much to be nailed down, so I probably jumped the gun...but I got excited because of the 20 year anniversary thing and my car's unique role as the first Superformance that came to the states. Sure would like to be there.
