I just got my GLI aligned yesterday at firestone (the same shop that the dealership sends cars out to for alignments). I payed 69.99 for a 4 wheel alignment. I noticed that on the alignment spec sheet they showed me that only the front two wheels had parameters. The guy told me that there is no rear wheel adjustment for our cars so I paid the one size fits all price and there was no way he could only charge me for a two wheel alignment.
Oh, and my caster angle was off but they guy said there is no adjustment of that on our cars. Any reason for this? No huge potholes hit, no crubs hit, and the car only has 12k miles.
