??? that doesn't sound right ,unless you did it yourself, parts alone surely would cost that? ie belt, pulleys,tensioners, and the following is also recommended to change while your in there: thermostat, water pump
if it was a garage that did the work, ask them for a breakdown of what they replaced.
Yep..got it done at the garage where I bought the car..he did it along with fixing in my new alarm. That cost me €120 also. Everyone else wanted to charge €300
