I don't doubt you got a smokin' deal. Resale values on Aprilias blow. (or rock, depending on whether you're buying or selling...)
They're AWESOME bikes. Incredible handling (only talked down about by the bike mags due to their lack of advertising $$$ spent), great power, etc.. They are, IMHO, the best bang for the buck on the market in regards to quality for your money. Fit and finish is second to none.
