Wow, it`s not often I see these wheels. I`ve got the same wheels myself, 7.5/8x15 with negative offsets.

Nice to see them on such a nice car, good luck with the sale!
Oh, and the reason why I posted... Is Riverside Star the proper name for the wheels? I know mine are Riversides, but I never knew the model name..
