And I'm sure that occasional recalibration is important when trying 
to make measurements to a fraction of a degree. It might be useful to 
ask when/how this machine was last recalibrated.

The alignment shop that I use is definitely old school. He does not 
have one of the modern alignment platforms with all the optical 
stuff. There's just one alignment measuring device and he calibrates 
it by sticking it to a metal plate cast into a nearby concrete wall. 
He can check that plate periodically with a level to make sure that 
it's still perfectly vertical.

I suspect that his system is not accurate to better than 0.1 or 0.2 
deg, but that's close enough. His big advantage is that he's been 
doing this for 40 years, so he's seen everything and nothing 
surprises him. When I first talked to him about doing a Type 3 he 
wasn't sure he remembered it correctly, so he started asking 
questions about the suspension. It quickly became clear that his 
memory was still good.
