He will not get asking price for that bike. Over 10k is just too much for a Prolink. Even for a low mileage and great condition one like this. 8k max is a realistic number.
I know there is the common perception that 1979 CBXes are the worth the most. Among long time (and multiple-) CBX owners this is somewhat controversial and never really quite understood. The performance advantage of the 79 over the 80 is just on paper. The hp difference is well within the manufacturing tolerance of an internal combustion engine. One contributing factor to the believe is, that early 80s had a faulty advancer that kept the bike from reaching its full potential. Many were tested and written about based on the poor performance and somehow that manifested itself in the public. Honda had a service recall for all early 469 advancers and they were replaced for free. So, a 150lbs rider on a 1980 will outrun a 185lbs rider on a 79. Believe me.
As far as value is concerned, as I said earlier, Honda made almost 24,000 79s. So, it is not really rare. And if low numbers would be a measure for value, the 1980 Japan-made bikes should be the most valuable. Less than 1,900 produced.
As far as rideabilty and "daily use" are concerned, the Prolinks beat the naked models hands down. Some weather protection, some luggage capacity and a chassis that's quite superior make these the better bikes for someone who wants to ride them now and then.
