M/B Parts and Labor
Brothers of The Benz, and Michael
I believe you're right relative to the warrantee offered by M/B on thier parts wheither new or rebuilt, purchased across the counter or installed by M/B.
That's the incentative to purchase OE parts.
With the exception of perishables, I will always buy from my dealer.
You should price shop for all dealers don't offer the same price for the same part.
