I would go with whichever bass appeals to you the most. I really don't think the quality of the CV line is so far above the VM's as to make a substantive difference. To me the differences end up being a matter of personal preference, I.E. Cv's high mass bridge over the VM's standard bent plate bridge (I prefer the latter) VM's Duncan Designed pickups over CV's standard pickups (the former for me), vintage versus jumbo frets (no preference on my part) the CV's Glossy neck over the VM's satin finished neck (again no preference) and color schemes (the only CV model's finish that appeals to me is the 50's P butterscotch blonmde) . The tuners on the CV are supposedly better, all I know is the ones on my VM's are perfectly fine, and seem like good quality hardware, thew same goes for the bridge and everything else.
When I was shopping for a backup bass to my MIA Jazz, I had zeroed in on both the VM and CV Jazzes, and form what I read the CV seemed to be held out as the better bass, but I found the white/tort/rosewood to be much less attractive to me than the natural/black/maple VM, so I went with the VM, and I am quite happy with that decision, it's as good a quality bass as you could hope for, and I doubt I would have been any happier had I gotten the CV. Getting the CV would have been a compromise lbetween looks and a minor bump in overall quality, the VM was anything but that. The exact same would go for my amber VM P as well.
That's my experience anyway, FWIW.
Having said all that, go with your gut feelings, either one of these, the CV or VM will do you good.
