If I were you I'd go look at the bike first, and directly ask/tell him that you are jotting down the VIN number to check car fax (if he is not a dealer, don't trust his carfax, spend that $40 on carfax), like this it gives me time to assess the bike and figure out if the deal is good enough or not. By doing this you are not carring cash on the first meet (I never carry cash on first meet if I'm going there alone).
