My car was recently repaired (turbo air intake motor, motor mounts, brakes) at which time I also asked them to do the annual NC safety inspection.
When I picked up the car and asked about the inspection, the shop rep said he couldn't do it because the car had just been repaired and needed to "run in" for a week or so before he could hook it up to the machine.
I've never heard of this "run-in" period before. Is this true? Has anyone else experienced this?
