I'd say that's a good deal for an SVT - if it's in good shape.
As with any used car with near 100K miles, expect some upcoming repair/maintenance expenses & don't mod it up right away. Tranny, fuel pump, & alternator come to mind. Get a feel for it's overall condition & be confident it will hold together before you start spending extra money. It is, after all, an SVT. It has likely seen some hard driving.
