I had taken my car to Tires Plus for alignment. When it was done, I asked for a report and they didn't provide one claiming their printer was choked.
When I drove my car back, the alignment was still off. So I took my car back to them within 5 minutes. This time, they did not do anything and only provided me with the report (all of a sudden, their printer started working). The same thing happened few months back with my other car, but at that time, they at least fixed the alignment.
I have the 3-year policy, but I guess they don't perform any alignment when you purchase the policy. If you pay for it everytime, they would do it.
