I also thought it should be about 4 hours... even the other technician said that. They are basically asking for $185 ($74/hour) more and with that money I can invest it by purchasing the Euro lights I want to get for my car.

I purchased a MB key since I only had one.. they said it would cost $50 so I said fine, I will still get it. I went today to get it and it and I was expecting to pay $50 but they said its only $27.50. Thats nearly half of what they told me. Do you think they gave me a high estimate on the water pump so the actual cost would be less? Should I tell them that replacing a water pump should only be about 4 to 4.5 hour? OR should I just forget getting it done there and have the other technician do it for me for $400?
thanks
