I'll respond here too (responded on facebook too

I personally would go with the 06 (even though I love my 03) because, as stated above, a lot of aftermarket goodies only fit on the 04 and up models. The 03 was really a generation of it's own and sometimes it's tough finding things that will fit.
I'd also be wary of that few miles on the SV - depending on how it was stored, you could be looking at a lot of dry rot (rubber bits and such) and brake line issues (moisture in the lines).
Just my .02
