2001 BMW 330ci • 6 cylinder 2WD • 147 miles

I was looking at a 2003 325i and when the car was started heard a noise from either the water pump area or alternator area. Once the car was warmed up and drivin I pop the hood and listen and didn't hear anything. Should I be concerned?

No. It is likely the deflection or tensioner pulley. It is typical and easily repaired.
