Made appt for my son’s Dodge Charger. We knew a new coolant thermostat was needed by previous IBD scans and codes. Told the mechanic what it needed. They charged $170 diagnostic fee along with $700 to put in a new thermostat. Usually the diagnostic fee is waived if work is done, but not here. Thermostat can be put in in 15 minutes. They also wanted to do coolant flush and other work to increase the bill. Won’t do business with them again. Took our car and paid the $170 bogus bill.
