From what i am understanding, right now they are going to have several connected events over the 3 days. An island tour using the old race route. A island ralley, and they will be using the airport for an Autocross/gymkhana. and then various dinners and island fun.
I saw some more event footage and pictures from last year and there seems to have been about 2 dozen cars including a lotus 11, various triumphs, a 911, a wierd 911 with a wierd front end, a 65(?) corvette, a big healey 3000, some odd alfa romeo coupe, various mga's TC's TD's, a bullet fendered TC.
