I would recommend taking the car to a shop that specializes in high-end cars and not to a discount tire shop.
I also would study up on how to lift the car and watch when it is done.
The car does not have to be lifted.
the tires are often on turntable pads so adjustment can be made w/o friction bind at the tread/floor interface.
If a car is measured, picked up,' then lowered again the alignment is off as the suspension will show positive camber until the car is rolled back and forth a couple of times.
Anyway Your point about knowing the procedures and WATCHING the work being done is vital.
Somebody on one of the BMW forums took his M3 to the local chassis dyno (live axle pony car experts). Didn't bother to watch. Rear was strapped using the rear driveshafts. car sustained rear suspension/driveline damage and accelerated wear of the clutch components etc.
Plus the shop only compensated for visible damage as the owner was not knowledgeable about the car.
