I did a DIY toe alignment at home with thread stretched between two jack stands and for the spreader bar I had 2 pieces of 2x4 lumber and a bathroom scale on either side of the jack - you may need to support this contraption.

I set the toe to equal distance and just a smidge more for wheel to point inwards. Car is rolling pretty good. For absolute correct alignment, the dealership should have the 5 finger spider that go into the wheel holes (the small holes between the lugs) so they actually measure from the hub. They should also use the spreader bar and follow the correct setup technique in which toe is set last.
