I just purchased a head gasket set for my '91 420sel from FastLane... it said it would be a Goetz set, but when it showed up at my door it was a product from Victor Reinz, a German gasket maker owned by Dana Corp. My initial reaction was, what the f***, so I looked at the Dana / Reinz website. They claim to be "the largest engine sealing provider in the world". I've heard of Dana, but not of Victor Reinz. Anyone have any experience here?
