The one that was off is a newer Garmin, installed along with the GNS430
by the previous owner. While I haven't checked the logs on this, I'd
bet it hasn't been tuned since then. During the first 1.5 years of
ownership, both VORs were never more than +/- one degree.

Although technically an avionics shop needs to do the adjustment most
owners puchase the spline screwdriver and do the adjustment themselves.
You simply remove the OBS knob (via set screw) and there adjustment
screw is behind it. Usually I do it as MHR or SAC where you have a VOT.

Hmmm, interesting...not something that gets logged I'd bet :-)
