[Porsche-O-Phile]

Well on the Mercedes, the O.E. windshields are made by Sigla and have a white rectangular thing in the bottom corner that says "authentic Mercedes-Benz product" (referring to the car, not necessarily just the glass). From what I can glean in the M.B. world, that's actually something buyers look for.

I generally don't trust aftermarket stuff anyway (and yes, I fully know the difference between "OE", "OEM", "aftermarket" and "reproduction"). If it's a product made by an OEM, fine I'd consider it, but I'd REALLY prefer to have the OE stuff installed. I plan on keeping this car a long time and would like to keep the thing as original as possible. I do think the SLKs will be worth something in the future and don't want to go slapping a bunch of aftermarket crap on it that will diminish the value in the long-haul.
