This is funny! I’ve owned Porsches most of my adult life, capable of nearly reaching 200 mph, and an alignment on them was < $200. But I was quoted nearly $1,000 by my local Dodge dealership for an alignment on my Gen III, so I guess Woodhouse might be letting you off easy at $600. My dealership said it would take about 7 hours to align the car; when I questioned that they said something about the car driving at 200 mph. There is no way that I can imagine a mechanic needing to spend 7 hours to align my car - but I suppose someone might chime in and prove me wrong! My dealership is worthless to me, but I’ve been to others out of state that are fantastic. I would recommend that you try a few other places. IMO this is a prime example for the definition of “The Viper Tax.”
