I live in Hawaii & just bought my 1st Busa (bike rider over 40 years, Harley's over 25 years,still have my Harley) last October, its a 2008 & had only 8,100 miles, paid $7,500. I know it wasn't ridden hard because I experienced hesitation @ 6,500 RPM & it was due to a clogged fuel pump, besides other issues. It looked really clean & still does, however, since this guy lived in a condo, maintenance was very limited. For that year, 2003, Gen i & price, I would shop around as there are always Busa's for sale & later models with low mileage. If it rides smooth through the gears, I would be concerned about what maintenance he did, or what work/maintenance was performed by a shop? Most guys keep records but don't give out this type of info, unless you ask for it, this may help you make your decision to buy or not buy. The Busa is an amazing bike, although it has its own issues, not trouble free as I previously thought, but its a bike that makes me smile more than riding my customized Harley. Aloha & happy hunting.
