My car was losing coolant from a small slow leak. Indy says it's a bad hose. OK so he also suggests changing a shroud and thermostat....They're not bad yet, he just recommends it. Is it worth $400 of prevention? I know how these guys usually don't like to let me go until I fork over $1000 every time.

I had the car for the last 3 yrs and the car has 123K on it. (60K on my Alusil actually) The previous owner noted some extensive service before I bought the car but I don't know if he had changed the thermostat/water pump. The radiator was replaced last year from an accident too.
