Hayes in Georiga? That Hayes? I bought my first Crossfire from them - and NEVER would I take a Crossfire there. Nice people, but they have no Mercedes experience.
We hold free tech days in Oakwood every three months - where have you been?
ANYWAY, I fixed mine myself, first time. It was the breather covers - common issue. Took a few hours (it was fun!) and cost me maybe $65 in adhesive, valve cover gaskets and oil cap gaskets and a set of bolts (the bolts that hold the valve covers and breathers on are said to be one-time-use bolts). Got the stuff at Needswings.com
