Hi Ed,
Well, we've covered the basics, I guess. The reason I suggested that the dealer is wasting your time is that if you do the same thing twice without an improvement, any subsequent efforts are logically not going to improve the situation. I can suggest a couple of remedies, perhaps. One has to do with the alignment procedure. If it was me, I would have the shop align the car with the drivers weight in the seat. The heavier the driver, the more important this is. Most shops do this, either by putting a mechanic in the seat while the technician is adjusting the toe in, or substituting weights for the driver. About the toe in, it should be as close to zero as possible, without approaching toe out.
It's kind of a stretch, but I would also consider doing the alignment with the ignition on and the suspension switch in the position that you favor most of the time. You never know what subtleties may be having an effect on the suspension. Also, consider taking the car to an alignment and/or frame shop and spending $100 to get an independent opinion. A second set of eyes may find something that the first set has completely overlooked.
