Do these repair cost quotes sound right? They seem pretty high. on 2004 Audi A4

Job 1: Replace engine coolant thermostat and temperature sensor $914.00 plus tax (My dash temperature gauge fluctuates from cold to middle of gauge during drive. This is the reason I took it in for diagnosis)

Job 2: Replace driver and passenger front suspension upper link inner bushings $776.00 plus tax

Job 3: Replace driver and passenger side engine mounts $1,010.00 plus tax.
