I owned a '72 Honda CB350 for many years. Rugged, dependable, solid, a lot of them sold, cheap (I sold mine in the mid 90's for $400 ... $150 more than I paid for it in 1980. In 1974 the CB350 was phased out and replaced by the Honda CB360. The CB360 was in production for 2 years, I believe, with 1976 being the last year.
You better check the dates, but I think from the looks of that bike it is a 1976 Honda CB360. It looks to be in very good condition, but it isn't a collectors piece, so value is in how much you will use it. I don't know the condition of your BMW, but I doubt Blue Book on a 76 CB360 is anywhere close to the Blue Book of a 96 BMW Convertible.
