There is more character compressed in a single XB than you will find in a whole truckload of SVs.
Then again, I am biased, cranky, and don't give a hoot about resale values.
How about this clipping, written by ol' Burnsie a couple years ago:
If all you want is cheap, go with the SV. If you're like me, you also want a cool motorcycle. Twenty years from now, you'll be able to stand around your lovingly cared-for Buell, which will be somewhat rare, and you can `splain to the kids how it was the first bike to carry its gas in the frame, first with the perimeter front brake, how you and Ann-Margret used to bomb round `Vegas on it. In other words it will still be cool. The Guggenheim might call to borrow it. Meanwhile, you might see the occasional ratty SV650 parked on the street in a shabby neighborhood or over at KPaul's with a plastic milk crate bungeed to the back seat and duct tape covering the holes in the faded seat, smelling of cat urine.
