Good points, slowmover.
I can think of an instance where VG's would help a 3-box sedan: as was pointed out by another member, if the car decklid is high/long enough that there is flow reattachment by its trailing edge, there may be little to gain in terms of wiping out the separation bubble via VG's
But if the deck is a little too low/short for flow to reattach after leaving the roof, and VG's could get the flow to reattach, then I think you'd have something worth testing further.
I can't think of too many cars that fit that profile though. Designers don't make aero mistakes like that anymore (complete detachment at the trailing edge of the roof on a 3-box vehicle).
