Bully for you! You saved 800.00 dollars! I have never pressured anyone to do a car or truck repair when I've quoted them. I tell them what I found, take the time to formulate an estimate, then tell the customer the TRUTH about the situation.... Does the repair need to be done right away? Can the wait to have it done? Can they do it themselves? Let them be in control of IF they want to do the repair, When, and by whom! I respect their choice.
As I've told MANY folks here and elsewhere; Find a mechanic when you don't NEED one.
As to the guy trying to upsell you an alignment, was his shop busy? What was his motivation? Did he have a brand new Hunter alignment machine costing north of 70 grand? Hard to say.
