Chris - I saw the ad for the CB750 in SA. That is an F model, looks pretty nice.
Has a few minor mods: paint handlebars and exhaust, bet you could get it for less than his asking price if someone else doesnt jump on it.
That seems to be a fair asking price for this market. If you looked at the 750's for sale in Austin, there are priced much higher, but arent selling...yet. A lot of newbies [like you!] buy in the Springtime.
Call him and ask details about the bike: mileage, running cond, how long he's owned it, etc.
Keep it on the short list but let's keep looking. KerryB's bike should be on the list too, only $1000 or so, plus $400 to ship. That's a good deal.
