I'm thinking of replacing all four door seals on my '83 300D. All of the usual online retailers seems to stock only Uro brand seals, plus for some odd reason a couple of them sell a Lemfoerder brand seal for the right rear window only. (???)

Are Uro seals a quality product, or is this something that one should buy OEM only, like most people recommend with the windshield seal?

If OEM is the way to go, does anyone have any idea what the dealer charges for these items?
