The gentleman contacted me as well regarding an inquiry I made for our members as to whether it was still for sale. He responded back that he needs some time to deal with important issues that are consuming his attention/time. He is considering holding off on selling it due to his other concerns and will decide within a week whether to remove the listing.
My suggestion to anyone interested in buying his ZR-1 is to empathize and be patient. Hopefully it will pay dividends if and when he decides to sell it.
