what to buy

[straw man]

So as much as I'd love a gen 2 given that I haven't ridden a busa for a few yrs I'm thinking there would still plenty of fun to still be had with gen 1 , I have found 99 black/ silver with 40 ... Ks or 04 purple/black with 80... Ks , both have asking price $6000 both look the goods , which sounds the better buy .I haven't asked about service history ,is that something to worry about ?

Any thoughts appreciated .
