A good local business will quote you a fair price for a repair service, perform the service with quality and integrity, and back up their work with a guarantee. You will leave feeling like you were treated fairly, but a little upset about the unexpected expenditure.

 A bad local business will quote you a low price on a repair, then introduce a series of setbacks and add-ons. You will leave feeling like you were cheated and second-guess your choices.

  A local business run by geniuses will quote you a fair price for that repair service, warn you that the price could possibly go much higher if things don't go well, then come in a little under their quote with a reassurance that everything went great and you have nothing to worry about. You will leave feeling fantastic that you just spent hundreds of dollars that you had no idea you would be spending just 24 hours earlier, but avoided a speeding bullet.
