Special orders like my dad seems to have gotten (to make up for an error made) seems to muddy the waters relating to waiting times also when they can add in a last minute order to right a wrong.
Was given the impression that if I hadn't seen the tracking discrepancy that i'd be none the wiser when my dad's correct car came through a few weeks after mine. It does mean though that the tracker does seem to be very accurate, as the reason for my dad's order anomaly is now known.
