Rear Shocks Replacement? Water Pump.

[babytic]

(First Post.) I have a 2007 Yaris Liftback bought new. 88,000 miles. Never had any problems except AAA Auto Repair, (Camelback Phoenix,) told me my water pump was leaking. They say its a "Corolla/Yaris" issue(?) They tried to show me with a flash light, but I never could see the green crusting indicating a leak. They also said the whole pump needed replacement. I though you could replace a gasket or something. Now they say one rear shock is leaking and therefore they suggest replacing both rear shocks. $500. I said yes and then called and cancelled. I have never owned a vehicle that needed shocks replaced. Did I just get lucky? I figured when I am jouncing down the road, that would be time to replace the shocks, but $500 sounds expensive. No? I have never had brake work done and the mechanics always think I have new brakes. Did I get lucky?
