Typical thieves! They charged me $570 to replace 4 $16 spark plugs with a $180 fuel system cleanup, which you can get at Walmart auto center for $30, as I learned later. The original quote was $1,600, because Alex (manager) alluded that the "coils" needed to be replaced, at a cost of $200+ each. I declined the coils, but when I picked up the vehicle, he told me that he had replaced 2 of them "at no charge" ... How generous, right?
