I'd just keep the '05 and look for something interesting to beat up around town. My first thought would be a BMW GS800. It'll be slower than the ST3 but it'll do everything plus you can just beat the snot out of it. And it's easy to work on, looks cool, isn't on every street corner, etc. Damn, I'm gonna check out Trader Online right now and see if I can find one for me. Maybe I'll pick me up an old Guzzi 500 or 650. Yeah, to hell with new; keep the nearly new and add vintage.
